i also tried using tubes on concert dvds but it did'nt sound good....

Am using a 1.5 watt per channel DIY EF86-EL84 amp (featured at the recent Alabang Audio show) driving my "Viech" (google "viech speakers") for DVD concerts and general DVD watching, and it is a lot better than my high-end Denon AVR!

For oschestral and rock concerts, am using my DIY SE KT88 and it rocks!

Synergy between components is the key to excellent sound. Tubed equipment or SS equipment will sound not as good if the components are not matched.

medyo mahal na masyado para sakin cayin

If you want a starter tube amp, Edrel Sison of this forum might be selling an EL84 amp based on the Zen circuit. PM him, he might offer a kit that you will assemble yourself or an assembled one. It is quite inexpensive, borrow his prototype and audition it.

Sir/s,
I am new here. Does anybody knows where we find/purchase vacuum tubes in Jeddah like 12AX7, 12AY7, 6418 or GE 6072. I am a fanatic of a high audio quality mic which can be easily obtain using vacuum tube. By the way I have a small home recording studio and some piece of pro equipments but still I am die hard of having gadgets that uses vacuum tube. Please let me know. Many thanks

It all started last year when I look at some Cayin tube amps catalogs at Festival Mall out of curiosity, then had that interest of owning one - for the start I bought a hybrid AV200 amp from Raon which I brought to UAE, have ordered a Yaqin MC10L but had no chance to test it when it arrived in Phil because I already left the country. Last night I received my order of SET FU50 and paired with my RTi3. I have ordered few days ago for a customized SET 300B from AMX to be paired with my RB3. After less than 10 months I have accumulated four tube amps. I don't know what's next? -tweaking the first 3 perhaps.

Mga master tulong lang po at konting clarification new pa lang po ako sa tube at gusto ko subukan mag assemble. Ang tanong ko po is, di po ba ang supply ng heater is 6.3v lang halos ang nakikita ko na mga schematic diagram is they are using 6.3 0 6.3 Volts sa secondary (naka ground ang zero) meron namang 3.15 0 3.15. di po ba if connect nyo ung 6.3+6.3 sa heater=12.6 V eh di ang labas over voltage ang supply sa heater. Ano po ba talaga ang tama (6.3 0 6.3 or 3.15 0 3.15).Salamat po sa mga sasagot.

^12 volts yung 6.3-0-6.3 volts, yung 3.15 0 3.15volts naman 6 volts.....

depende sa tube type, kung 12AX7 pwede mo gamitin yung 12 or 6 volts depende sa wiring mo yan...

kung 6BQ5 naman, 6volts ang pwede mong gamitin...

Hello po mga Sir. May tanong po ako, meron po kasi kaming old phono stereo system local lang ata iyon. Ang brand name niya ay "RADIOWEALTH" if I'm not mistaken, my father bought it during the mid 80s siguro. I believe it runs by tubes kasi I remember there is light inside the system and you can see it glowing at the back ventilating cover made of plywood i guess. It has Turntable, AM/FM tuner and a couple of AUX (RCA) connections.

Ang question ko po is,

1. pede ko pa kaya bunutin yung main unit (receiver/amp) from that huge box so I can use and place it on top of a table something?

2. can I use it as an Amplifier since it has two AUX connections?

Wala po akong picture or I can't take pictures of it, nasa abroad po kasi ako. Naalala ko lang kasi yung stereo nang Tatay ko na palagi nyang pinatutugtugan nang "Marching Bands", "Sinatra", "Presley" and "Nat King Cole".... Hanep sounds nang Tatay ko!

I hope someone can answer my questions!

Thanks! Have A Nice Day All!

Thanks you sir!

Make sure if its working before you test it. Most likely capacitors are already dead....Send this to a good tube technician to test it.

ATJr. · « **Reply #555 on:** Sep 25, 2012 at 03:36 PM »

yes, you can also wire up a 100watt incandescent lamp in series with the power line to the unit....this serves 2 prupose, first is to limit turn on surges, and second to serve as a safety device in case there is something wrong with your unit......make sure na hindi pinamahyan ng mga mababait yan at hindi kinagat-kagat ang mga kawad sa loob....these thind happen to old sets....

noob question :
1. is it advisable to connect a tube buffer to a hi end cdp and to an entry level amp/pre amp? would it elevate the sq of the set-up or magiging palamuti lang sya?

2.which is better to connect the buffer? cdp >> buffer>>>pre amp>>>poweramp OR cdp>>>preamp>>> tube buffer>>> power amp.

any inputs will be appreciated. thanks.

ATJr. · « **Reply #557 on:** Nov 27, 2012 at 06:26 AM »

1. depends, i use buffers on dvd players to playback stereo, YMMV...
2. a buffer has no gain so you can connect it any which way you like, try both and select the connection that sounds music to your ears...

hi guys,

this is a diy hp tube amp i got from a diyer from another forum:

questions:
1. anong family of tubes po ang gamit dito sa amp ko? may nabibili bang tubes like these locally?
2. what other mods can i do to improve its sound besides tube rolling?
3. who here in manila can do mods for this?
4. can i install rca ports so i can use this as a pre amp for my ss amp?

Thanks.

Mga tube gurus. Tanong lang po ako about tube amps for headphones. Ano po kaya maganda for headphones at kung saan po makakabili. Salamat po and more power
