i think masyado nang marami na ang nag post ng should i say negative things about tubes......kaya naisip ko na mag post ang mga experts on tubes tungkol sa mga good points ng tubes....for our information din po ;D
-
i never loved TUBES, much as i never loved SS amps either, i build them, use them and sometimes i get lucky i sold them.
To me LOVE is a term you use on people, you love your wife, kids, family and friends, amps, we use them.
It is indeed sad if we used people instead and loved tubes...... ??? :o ::)

sabi ko na ngaba medyo mali yung subject header na to eh :( let me re-phrase then......Whats the biggest reason why you like to use tubes?......sounds better? :)
-
Tubes are very musical and I enjoy my music more.
-
tube amplifiers done right sound very musical
-
biggest reason = i heard them and i liked it
before that, the biggest reason i haven't gone into tubes was i didn't know how it sounded, so i considered it risky to spend that much for so few watts.... but now that i heard some that were "done right", i'm posting here instead of the other thread. ;D
-
I believe the more apropriate phrase should be - "in general, tube amplifiers sound very musical
specially in a SET configuration".
-
just for staters can you please post some tube brands that are a good buy and that are suitable for us beginers ;Dand the reason why?!

I used to be a solid state die hard. HEADBANGER ako. I have this negative thing against tube amps based on what I READ although I never heard one.
Then I got an AMX EL84 tube amp. Rock music became pleasant to my ears.
Now I prefer to listen to tube amps.

magkano po ito sir and san pwede marinig to ? :)
-
the el84 integrated costs 12,500 the last time i checked, right now they only have the integrated el34 amp for 17,500.

thks sir nakikita ko na nga yan...pero parang nakakahiyang pumasok :-[ kasi parang nakakahiya pag canvassing and audition lang ang gusto mo ;D
-
elvenears: they're accomodating naman, although the place is not really ideal for demo. Just tell them you want to listen to a particular amp they'll oblige.

Pasok lang and audition.. sabihin mo kilala mo si John5479 hehehehe
Love tubes kasi type ko tumunog.. ;D ;D tska kakaiba ang looks. ;D ;D ;D

pero pinakakilala dun si sir AMXtube. ;D
pasok ka lang and say please. ;)
then you'll have a taste of the "biggest reason" your looking for. ;)

Like most, i love tubes for their warmth.
Tubes to me, stands for a romance with music.
You know that your manually wound watch will never be as accurate as your digital
plastic one.
But this romance is best set against the manual movement of a finely crafted timepiece
than in the clinical precision of quartz.
The way this romance is best felt in the midst of these sultry "fire bottles" than the
dark corners where capacitors lie.
whipsaw

dark corners where capacitors lie
... all topologies use capacitors. ??? One just needs to understand what their disadvantages are for a given application. ;D With correct usage, capacitors are in fact a gem. ;) We need capacitors, just like we need transistors, FETs and vacuum tubes. I myself don't love tubes much as I don't love any electrical component. Like what Sir 2ny said, I just use them to the best of their abilities.
Electrical components designed and layed out properly beats the hell out of the vacuum tubes vs SS argumentation. ;D ;D ;D
-
any suggestions on on budget tubes for beginners ?
-

the best capacitor is "no capacitor" in a signal path, a good designer will try to avoid them whenever he can, or at least keep them to a minimum.
-
indeed true! ;D

Can't avoid if unless you want to couple dc to output. Need very tight tolerances and tight pcb trace loop areas. Not good if you have lots of parts. Performance vs cost penalty (also include development time).
If you have caps too low signals can bypass this specially if you have several components connected to this. Need to put cap footprint on PCB trace edges to ensure max filtering.
If you have caps too high you will have discharge problems.

Push pull muna around 30 watts would be fine.. except you have high sensitivity speaker then try mo SET.
AMX would be good starter. :)

Circuit design ng amp i let the tech guru to ask futher.. pero for 9.5 Push pull would be a must. ;D

Hi,
I'll try to keep the technical mambo-jambo as far away as I can.
Music (or audio frequency) is made up of modulated sine waves. A whole sine wave is made up of a positive cycle and a negative cycle, where the two crosses or meets is known as zero crossing.
With this in mind, a push-pull configuration uses two output tubes wherein 1 of the output tubes amplifies the positive cycle and the other 1 amplifies the negative cycle. This action then denotes a push-pull action because when one of the tubes "push", the other one will "pull" when the first one approaches zero crossing. Push-pull amps vary a lot due to the different types of biasing and their operating Class but generally have higher power capabilities.
On a SET (Single Ended Triode) configuration, there is no push-pull action since there is only one power tube and this tube amplifies both the positive and negative cycles of the sine wave. This type of amplifiers almost always operate on a Class A biasing and power output ranges from 1W to 15W only. So these type of amps would require a fairly high sensitivity speaker to fully realize it's prowess.
Hope this helps...
JojoD

All these technical jargons can screw your brains out, after all, what we want to listen to is music. At the end of the day it's our passion for music that drives us to sit down, relax, and listen to our favorite tunes.

thanks for the answer sir jojo.....medyo may naiintindihan ko na !!!!your right at the end of the day we just wants to listen and relax ....but its that same passion that drives me to also learn these things.....i do understand that ears are always the best tools but having technical know-how would help rite?!?having said the thing about ears.....mga kapwa members!!!!ingatan natin ang ears natin!!as one of my friends from pinoydvd once told me "kahit saang audio shop wala nyan" ;D

Sir, I'm interested sa sinabi niyong audio lies and myth. Can you give as an example para well-informed kaming mga
ngayon palang sa tubes?
I have also have several observations (i accumulated over a year) pero I'm very careful not to offend the feelings ,kasi
parang religion ang dating ng hobby na ito sa iba?
But I think in pinoydvd forum , lalo na mga nagtatanong importante ang ma well-equipt sa info kami.! yun ang importante
-
I'm interested sa sinabi niyong audio lies and myth.
here is one,http://www.hardwareanalysis.com/action/printarticle/1790 this has been discussed here at lenght and there are several others.
if you want to know more, you can google, audio lies and myths.
in this hobby, there is such a thing as "high end" audio, and you are not "in" if you are not into it. but to me high end need not be at such ridiculously high costs.
you will see those afflicted with this sars, buying gears then later selling them for even more expensive ones, this type of obsession once it bits you will be very hard to get rid of later on.
that is why DIY is the way to go, even if you spent a lot of money, you know where the money went.
-
if i may, some i PERSONALLY consider as such...
1. x tube will always sound better than y tube. (can't be treated in isolation from the circuit that uses them)
2. negative feedback is absolutely bad therefore not to be desired
3. triode is better than pentode or vice versa
4. SE better than PP or vice versa
5. NOS tubes can beat new production anytime
6. inexpensive gear inferior to "hi-ends" in terms of sonic qualities (same with choice of exotic vs standard parts)
7. XYZ circuit (say DC) will always beat ABC circuit (say RC).
now, maybe these are my own biases ;D. honest truth is, i sometimes distrust my own senses (often easily clouded by biases) and will only do so trust my ears esp during my own blind tests.
btw, there are some many writeups that support and contradict my list above. after saying this, am sure you will not be as enlightened as before reading my post. :)
-
eto na ang mlupit na tanong!!!!!!!sino sa inyong lahat na nagpost dito ang pwedeng magpahiram sakin ng tubes? ;D
What kind of tubes? Driver, Rectifier...etch? I assume Tube amplifier, Push-Pull or SET? ULtra-linear or Parallel SET? Integrated or Power amp? or possibly monoblock? just kidding. Maybe it's better to join some listening sessions rather than borrowing them, unless you are decided to buy one (some stores can let you home audition them).
Now back to the topic "Whats the biggest reason why you love tubes". For me they produce better sine waves output.
-
Why do we like tubes? One thing I observed is yun MIDRANGE buo. Kahit anong type of tubes !
Pag nakininig ka ulit ng solid state, yun agad mapapansin na iba ang quality ng midrange pag tube amps.
Well I Visited the website suggested by 2ny, I agree with the observations. With regards to value of
tube amps sometimes talagang overpriced to make a impression that it is the best but if you open it and
compute the parts inside it is really way way overpriced. DIY NGA TAMA
NOS aren"t neccessarily superior to current produced tubes .
Mahal sila becoz the law of supply and demands applies.
-

no one wants to listen to sine waves! you can go deaf in time and have your speakers burnt to a crisp ;D
-
on tube rolling:
there are no bad tubes, only bad designs and lousy designers! ;D
-

How? Pls remember that both SS and vacuum tubes are used in civilian, industrial or military applications whether it be high frequency or otherwise. The accurate reproduction of signals is paramount. Perhaps you meant you like amplifying devices such as tubes or solid state that are designed and manufactured properly.
-

Yep ... I use a signal generator lots of times and I can't hear a thing whether its sine, triangular or square wave.
-
unfortunately for us pinoys, we are a people that are clanish and cultists, that we see more the person rather than what the person is trying to say. we see this pattern replicate over and over in almost everything we do. it is in our physce so to speak.
now going back to this hobby, a person with engineering training will not have a hard time understanding the principles involved, yet unfortunately it is these same people who capatilizes on the ignorance of many with the sole motive of reaping huge profits, making audiophiles spend more money than they need to.
so it is always best to learn as much as you can. para hindi ka mabola! ;D
-
Sir 2ny, sino sino itong mga engineer na ito? :)
... napakaraming kung anu ano ang sinasabi wala naman scientific basis. O di kaya binabaluktot ang scientific explanation. ::)
-
oh, i am not refferring to any pinoy in particular, but you see them on the web all the time, they are all over the world! read what they say and you will know! ;D
-
napakaraming kung anu ano ang sinasabi wala naman scientific basis. O di kaya binabaluktot ang scientific explanation.
comments that do not offer any scientific explanations are at best "social comments" and are to be treated as such, they are not worth anything.
why? because with such comments as "i heard an audible difference" there is nothing for you to measure, replicate and find out by yourself. so how can such comments be of use to you?
ang maniwala sa sabi-sabi, walang bait sa sarile! ;D
-
not to leave you empty handed, here is a sample of what i consider a usefull comment"
"changing operating points from 150volts plate to 200 volts plate gave sinificant improvement in sound, for my 6sn7 line amp."

one of the reasons why tubes? - because you want to try it? or na-SARS ka?

Sir correct me if i'm wrong our amplifier output is an AC wave, one reason that our speakers burn if your speaker received a DC.
If we can check the output of our speakers in oscilloscope its AC wave or sinewave right? Again correct me if i'm wrong, I'm not an expert. I'm here to learn not show to that i am dumb ;)

yes it is AC becuase it(music)has a period and amplitude just like a sine wave, but it is not a sine wave! it has pitch, but it is transient, not regular like the sinewave. it may not even be symetrical like the sine wave, meaning the positive and negative peaks may not be equal, it being transient in nature. hope you grasp my meaning.
hey, don't worry i am more dumb than you think you are, relax. ;D
oh and speakers are damaged in two differnt ways, one is thru mecahnical, meaning the voice coil bottomed out and when the voice coils burns out, one is by dc current high enpough to melt the wires and coil forms, the other by continous sine waves of even low watts, i have experienced this myself that is how i know. ;)
-
OT: "bottoming out" -- someone used this word before to describe a speaker driver's incapability to respond to the demans of the material on playback. for instance, a war scene and the speakers kind of choking due to perhaps to very low freq (drivers are full range/no filters).
can this type of bottoming out damage the driver?
-
probably yes because the voice coil is already hitting the backend of the magnet assembly. repeated hits can deform the voice coil too.
severe clipping can also damage speakers, this probably falls in the dc current cause because the burnout is caused by too much current passing through the coils.

remember that the speaker cone assembly has mass, therefore inertia and when in motion it is the ability of the amps to damp the speaker movements that is key. parang kotse na mabilis ang takbo, hit the brakes hard and you are liable to go siyete. same principle applies.

hala... kung ganyan ang attitude mo sa mga projects ay dapat mag build ka muna ng patience at perseverance aside from basic electronics. sometimes projects can be frustrating, but you have to learn how to convert frustration into excitement, look at problems as challenges.
Thomas Edison failed a thousand times before he was able to make his first light bulb to work. Yet he didn't waste his time for a thousand times, but instead, he learned not to make a light bulb work a thousand ways.
and of course, you have to find the "reason" to drive you. this applies to ss as well.
best regards

Sound waves is Analog & TUBE is an Analog Device:
"Audiophiles contend that tubes are better than solid-state principally for Amps because the former generate Accurate Sine Wave Patterns when reproducing recorded sound. The Tube is an Analog device so the sound it produces is natural and therefore more musical."
(Taken from the "Tube Amps in Digital Age" article from one of AV magazine)

How about 'electricity', 'heat' and the other forms of energy?
Are they also analog? ;D

Very interesting...
During my days, analog is a form of transmission that is a continuous "wave" electrical signal that varies in frequency and/or amplitude in response to the variations of a physical phenomena such as human speech or music. Hence, conventional TV, AM and FM transmissions are analog. An analog signal can even contain a carrier and a modulated signal in the same wave.
Electricity, as you said is also in a form of wave, however it is not modulated and only has a single frequency so therefore it is not an analog signal. Unless you vary it's frequency or its amplitude of modulation, electricity will always be a source of power and not an analog signal. However once electricity is varying then it can be "analogous".
Heat on the other hand is a form of radiation, unless it's radiation levels varies in response to a control signal then it is not analog. However, an oven with a thermostat and timer (control signals) is a device that varies heat radiation and is therefore an analog device.
Another definition of analog is:
An analog or analogue signal is any continuously variable signal. It differs from a digital signal in that small fluctuations in the signal are meaningful. Analog is usually thought of in an electrical context, however mechanical, pneumatic, hydraulic, and other systems may also use analog signals.
Small changes my man, small changes.

ANALOG: "time" displayed by mechanical clocks, "temperature" displayed by mercurial thermometers, "voltages and currents" of ac waveforms displayed thru meter-movement type voltmeters and ammeters. "analog" because we have to know how to read scales and meters.
DIGITAL: in a sense that we read them in numbers without so much of thinking. "digital" is when those above analog quantitites are converted into "1's" and "0's" thru the use of transducers and A2D converters.
these are all there is to this. very simple concept. ;D

I think the magazine could have described it as "more accurate analog waveforms" instead of sinewaves...just me.
-
"more accurate analog waveforms"
this is a meaningless phrase imho, for how do you measure transients? how accurate are they really reproduced?
most THD measurements are made with sine waves, and music is in no way a sine wave, the way we know what a sine wave is. music is all about transients, attack, decay, pitch and sine wave is just but a component of music.

http://www.meta-gizmo.com/Tri/index-1.html . an interesting read. i don't have any preference whether its tubes, solid state or what not...as long as it sounds good to me :) Do read the articles as it is and take it with a grain of salt.

since i started reading some electronic articles im beginning to understand this jargon little-by-little......salamat sa mga tips mga sirs...........another question ........based on comparison i think ss amps are more complicated ,,that is probably one of the reasons why some of us are fascinated by them...i really dont know how to rephrase this question so i would'nt be off topic but i just cant find a way, so here it goes...........if tube designs are simple?bakit yung mga nababasa ko pwede kang makuryente at mamatay pag nagkamali ka?is this true?natatakot tuloy ako!!!!!!also 1 more thing may mga hindi ako maintindihan sa mga diagrams yung symbol ng tube sa schems may dalawang tail at lagi tong nasa ilalalim !!does these tail connect to the power supply/transformer directly? ;D

do not believe everything you read, hook line and sinker, maliligaw ka nyan, article on audio specially tubes are more often than not about personal prefferences of the author more than anything, specially if the article does not disscuss technical matters, just opinions. it is very easy to spot technical discussions, all bases are covered and figures can be verified and checked.

if you are just going to follow schematics and build amps from those, then for as long as you do it right, it becomes a no brainer! tubes or ss parehas lang yan. kaya lang with tubes, higher voltages are involved, that is why electrical safety is a must with tubes more than with solid state.
it is when you want to design and build ss or tube amps from scratch on your own, (not the copy cat style design!) that you need to know all theories involved. and if you have say, an ee or ece engineering background, then it could be easier for you. i remember in college we had several units of electronics subjects, but they never theach you how to design amps.
the symbol you are refering to could be the filaments and they connect to the heater winding of the transformer, some or most schematics do not show this, given na yan, like it goes without saying. ;D

elvenears,
an ss amp, for example, a super leach power amp powered at +/-95V can also be lethal. so wether ss or tubes, try to be safe for these voltages can can separate your soul from your body. ;)
what do you have in mind? would you like to build a preamp or an amp? if this would be your first project then try a simple one first.

trust your feelings... feel the force flow.... and donot underestimate the power of the darkside.
::)
so do you love (meaning like - not in love per se) tubes? ;D ;D ;D

whats the biggest reason why I lovetubes?
for the warm, smooth and musical sound they give ;)

kasi gawa ni sir jojod. hahaha...
thanks nga pala ulit sir.
malapit na ulit tayo magmit. ;)
