schematics are very similar to audio note m10
output transformers made by AE transformers in your country

Whoa, really fine work and a sophisticated design. I'd love to hear that system!
You have had this built for some time right? This (attached) IS your build posted on an other site right? I have admired this since I first saw it! Beautiful work!!!

if you would be closer
.sounds very good,I am very happy.here is video (unfortunately bad video and sound quality)https://www.youtube.com/watch?v=MPj6kJofSY4

The video is cool, nice choice of music too.
If I had my way I'd become a reviewer of all serious DIY builds around the country. Man what a fine job that would be!
Unfortunately, someone else won that power ball thing
Yes, it's mine ! Since I build them few years ago I had some little unwanted ''hum/noise'' coming from the amps, then two weeks ago I decided to cure the problem thinking that the wood covers that replace the original metal covers where responsible for a lack of shield but it's not the case. As we can see, the transformers sit on rubber feet isolating the transformers from the ground, so I just cure the problem by adding a ground on each transformer and now the amps are completely ''silent'' from unwanted ''hum/noise'' !
Right now, I'm working on a new project ... I'm building a pair of speakers enclosure to match my amps, I bought on E-Bay a pair of Altec Lansing 601C 12 inches duplex speakers with the original crossover, the ''box'' are my own design, inspired by the Altec Lansing Stonehenge I, can't wait to listen to the result.

holy crap just watched the youtube video
what a stunning amp you have built
Those Altec 601s should serve you well
and you are obviously a very talented wood worker 
! I'm surprised though that you do not choose to stand once again on the shoulders of your predecessors. Design your own speaker enclosure? It's not as easy as designing a house...

now playing......EL34 parallel push-pull inspired my Marantz 9 monos...
uses the A431 OPT copy.....
input is a 6J32/EF86 pentode, then the 6RRH8 LTP phase splitter driving a 6CG7 cathode followers....
now tweaking to resolve some minor issues.....
preamp is a CCDA 6H8C/6SN7 fed from my MD player playing Bread songs...
Hi, I'm looking for a schematic with EL34 in PPP as what you have built, you may post the schematic? Thank you.
i suppose i can, the amp i did was cathode resistor biased with separate resistors per tube,
reason is so that the end user need not bother with bias adjustments n the event that tubes need replacing...
the power transformer is not available anywhere as it is my own design and build...
but i am willing to give winding data to anyone who requests them via pm...
the psu is a voltage doubler and large caps were used n the psu filtering...
i can hand sketch the design when i find the time...
my first amp
This is the first amp that i have buil with a personal interpretation of this http://www.diyaudio.com/forums/tubes-valves/158322-my-kt88-williamson-amp-build.html
