the driver stage is Russian 6F12P, Triode-Pentode.
a total filter capacity is 870uf.
Nice amp, Can you share your schema?
I have 6f12p's and 4 6ca7 maybe i can try...how the sound?
Looks pretty cool. Nice job. What do you use for speaker? And just because I'm curious, what guitar do you play?
A while back I built this small guitar amplifier with all octal based tubes.
- 6SJ7
- 6SL7
- 6V6
Controls are:
- gain
- bass
- treble
- master
My humble contribution. It started as a Stereo 70, but the only remaining original parts are the chassis, cage, outputs, and fuseholder. Curcio cascode 6922 driver, triode wired, beefed up stock supply with lots of by-pass caps. It has been making tunes in my system for 20 years now.

I assume all is now running well..

Ha! No, this pic is from a few years ago. It's changed again since then. I"ll have to wait for some new bias supply parts in the mail, but all the tubes have checked out OK.
Thanks for the advice.

Poor quality photo, but Happy New Year!.
I hope we can get in 2014, many new tube projects.

An externally hosted image should be here but it was not working when we last tested it.
You've got some great looking (and sounding? ) amps there... I'm very impressed
I nearly completed my recent stereo amp:
Two 807 SE, one 6SN7 and EAM86. Only the Volume knob is missing yet... It isn't that easy to find one as big as I want it to be
Maybe I'll do one of hard wood...
Best regards

Very nice and clean looking amplifier. I like that EAM86, does that vary with the volume level? Also, is it some weird error or is there really a blue blow in those 807's?
Thanks It took some time until I was satisfied with that veneer...
As the picture is long time exposed (ca. 10s), the tubes' light effects appear to be a bit too strong
The EAM86 works as a simple volume indicator, i.e. varies with the music. Actually there is a faint blue in the 807s that can be seen even at daytime.

Finished my tube rectified cd transport (transport only...roughly based on a Shigaclone print and laser...thanks to Peter Daniel thread)
Wow, that looks stunning!
About 100 watts. EL34 * 4 with ECC83 gain stage and ECC82 phase splitter.
Push pull pentode mode output.
Wasn't quite finished here. Plastic film cover needed removing and pot s needed cutting down and knobs screwed on.

Oooohhh yes. EAM86 is IMHO one of the most magnificent magic eyes.
Since my camera broke, I only have a very abd cellphone pic I just made:

Monoblock with EF40 driven EL38 with EAM86 "eyes". Rectified by PY81. Some years ago you pick up those tubes for a buck each.
