how many hours na nagamit yung tube?baka malapit na sa end of life nya yung tube.performance wise it is still better than the stock shuguang pero ang problem baka 10 oras mo na lang gagamitin then pundi na.ask the seller how many hours used.

[tinabal]

about 100hrs yun ang sabi, I don't know if it is true  , mura kc. bro roch malaki ba tlaga difference sa sounding? kc yung mallard npaka mahal yung 4.

[tinabal]

gusto ko kc talunin by far yung Anthony gallo ko pra approve plagi c mrs sa mga upgrades for now kc d pa sya masyado na impress compara sa home theatre namin.

On your end alin mas maganda tumunog yung ht nyo or the stereo audio setup?kasi kung para sayo mas ok sa audio yung ht maybe theres a problem with your stereo setup.

Ano ht setup mo?and how long do you listen to your tubeamp?if your just listening to it for like an hour each session then your not getting the best out of your tubeamp.

Sometimes iba then ang perception ng tao about sq.yung iba basta malakas maganda na yung iba basta malakas bass maganda na sa kanila kahit walang mid and high.
Try also mix n match with other gears and/or ic and speaker cable.
Havent heard an anthony gallo kaya i cant comment about its sq vs the el34 i only owned a yaqin mc10t for almost a year kaya medyo kabisado ko na tunog nya specially using the stock tubes

[rochie]

Btw kung 100hrs lang nagamit medyo mahaba haba pa buhay nun,kumbaga breakin period pa lang yun

[dodie]

chief anong tube amp gamit mo?

[tinabal]

boss roch, yung gallo ko nka kabit sa Yamaha tpos yung player ko ps3 lng sharp kc masyado yung gallo yung mabasag na baso sa movie tsaka mga instruments sa kanta talagang lumilitaw, about 3 years na yun, performance wise for me, prang my edge ng konting konti yung stereo, im thinking bka dahil sa dac ko kc muse lng yun tsaka source ko is MacBook. kc sa wiring mlaki masdyo deperensya yung gallo ko $2.5/meter lng nung brand less pa  yung stereo ko gumastos ako ng $140 sa 5m kasama banana plug sa hifi store.

[dodie]

i havent seen yung list ng gears mo below....btw maganda yang mc10t, pero yung iba natatalasan. proper matching lang yan ng speaker sir. lagyan mo ng faber yan, biglang neutral yan.

[tinabal]

marami nag sabi even d2 na mganda yung yaqin. 2 lng suspect ko DAC & source ko wla pa kc budget kaya stayput muna bka tube unahin ko palitan kc stock yun chinese tube.

[rochie]

ganyan ba sir yung gamit nyo na DAC? it may be your dac and source na nagiging bottleneck,if you can borrow a cd player para ma test mo din much better.in my experience pagdating sa speaker wires hindi ganun ka significant ang improvement pag nagpalit ka pero sa IC mapapansin mo.

[tinabal]

oo yung silver nyan. bka nga dac tsaka player ko. ipon nlang muna.

On the MC10, the biggest sound difference can be achieved on the pre-stage tubes. The EL-34 is the power tubes which will provide minor sound improvement unless the Pre-stage china tubes are replaced. HTH!.

this means that if i replace my electron tube el34 with svetlana will give a huge improvement? i hope so i'm craving that clear crisp sounding.

sugal yang pagbile ng second hand, unless you can test those tubes before paying out.....china tubes should not be looked down opun, i made two Shuguang 2A3 sets that sounded very well...

brand new JJ EL34 tubes can be purchased here...http://www.epektos.com/product/bdf34f81-3e27-4270-b471-8da91a5e150e.aspx

whoever said that china tubes are bad must be selling Russian tubes....
the weakness of China amps that i can see is not the tubes but the irons, or OPT's, they are small for my liking...
a tube amp rated 50watts at 1khz is not 50watts at 20hz, more like 15 watts, ditto at 20khz....
and this is what those tube amp vendors are not telling you....

maybe yes, maybe not, a lot of factors to consider, your speakers for one, your listening area, and your listening habits will be the final arbiter....

oh yes, the preamp tubes serves as the tone control, replace the tubes and change the tones....

sir AT, any recommendation tubes to replace the 12at7 chinese tube?

Before the power tubes try changing the pre-stage tubes first. PM sent

I have personally experienced Chinese tubes with open heaters and having red plates within 100 hours of their lives.

I also, personally (meaning me, I and myself) experienced an EL34 from JJ doing the dreaded red plate and the other one having internal sparks or arcing.

I also personally have EL34 (I have 3 quads) from Svetlana and 6CA7 (I have 2 quads) from Electro Harmonics which passed their initial 20 hour test runs. And no, I am not selling Russian tubes (no pun intended). The only Chinese power tubes I have in my collection are a quad of Shuguang EL34-B.

Another observation I personally experienced with some stock Chinese tubes is that they tested weaker than their brand new counterparts.

Please don't ask me if I biased the tubes correctly or supplied the correct plate voltage as I will just sadly take that as an insult.

Just sharing.

Cheers

Sir Tony,

Ok ba bumili sa epektos.com? Parang ang mura ng tubes nila, halos presyong U.S. na rin?

In the end it all boils down to your preference. Others may have said na maganda yun yaqin and yet you are still craving for that clear crisp sound meaning it's not, to your tastes at least.

If I were you, my first move will be to purify my source, the MC10 is an integrated amp so remove your DAC and take your source as it is. If nothing happened and it still isn't crisp sounding then would you agree it isn't the DAC? Maybe it's your source then? You may also want to take a look at your speakers but if they sounded crisp before then I'd look somewhere else.

Second, looking at the schematic of the MC10, I'd go with Cooltoyz's advice of changing the peanut tubes first and just let the power tubes serve their purpose and die of natural death.

My 2 cents only.

i have tried taking off the DAC, so the means of connection from my source is thru earphone jack pero ang outcome is mahina yung left speaker its like your only using 1 speaker, so i put it back in.

Sir Tony,

Ok ba bumili sa epektos.com? Parang ang mura ng tubes nila, halos presyong U.S. na rin?

marami na akong nabileng tubes sa kanila, so far no problems....
afaik, the tubes are shipped from the states, they buy in bulk so they can get a good price,
 JJ is a good brand...

[ATJr.]

sir AT, any recommendation tubes to replace the 12at7 chinese tube?

you can try the 6201 or the JJ 12AT7/ecc81,  if you want to lower the gain you may want to try 12AV7,
you can even try the 12au7 for even lower gains...

jojo, i am sure you did experienced those...

 tube amps are unlike SS amps in terms of maintenance....
pwede kasi tanggal kabit ang tubes kasi naka socket, try doing that on an SS amp....
and that in terms of reliability they can have short lives as in pag naibagsak at nabasag....
one of the pitfall of tube rolling is when the tubes roll down from the table a into the floor,
thye make such a distint sound of braking glass......
no tube amps are bulletproof, even the branded ones suffer breakdowns just like any other
electronics...

boss AT ganyan ba tlaga dito? it seems that other member cannot accept that there are much better that their rig.

[tinabal]

di naman sir, you need to be open minded and patient. ano lang naman yun parang debate its up to you kung accept mo or hindi we have different taste when it comes to music and audio hardware likes. minsan nagkakaroon ng mainit na debate pero pagkatapos nun e balik sa normal. kung san ka masaya thats good for you kung saan sila masaya well ok din naman yun.
