Neat balanced headphone amplifier from Bottlehead. Uses 12AU7 for power and two 6C45-Pi. This build features a powdercoated antique copper top plate, copper-leaf wood base, big 10uF Jupiter capacitors, and classy Cardas copper wire.
Enjoy the pics! Build log with lots more photos and details here.
Looks like a million dollars! Incredibly nice build, I love the smooth control plate and knobs WOW!

Guess you've been watching the news. Leonardo's painting will fetch way more.
This is a tough crowd for 'arty' pieces though.
Not sure I follow... there are plenty of artistic pieces in this thread made by people many times more talented than I.This is a tough crowd for 'arty' pieces though.
Last my experiment: 2x1 W SE 6П9 Russian-60s & PCC88 Tesla - incredible details, deep sound /in my 96 dB speakers/ from this metal small tube, that Russians use for driver for 6S33S, 6S41S, 6P45S,....and for big high voltage power tubes....IMO better than 6E5P, 6J4, 6J9P /6Ж9П, 6Ж11П/...

Here's this week's build.
You've gotta' hear this flea watt 2 watts/channel setup. www.youtube.com/watch?v=QHZtVtAzYvw

Single ended EL85 amplifier
This is what I build last week
2 watts per channel EL85 single ended 'power' amplifier, based on the RH84 rev.2 (with auto bias) schematics by A. Kitic.
ECC81 driver, with an EZ80 for rectification.
Featuring 5 watt Hammond output transformers, power transformer is custom made at HB amp design in Germany.
Uses 33 watts in total which isn't much considering it's a class A tube amplifier!
Sound quality is really neat.

I built a preamp
Full tube consruction. 6C5S rectifier, ECL85 / 0B2 voltage regulator and line level amplifier with 6N2P-EV and 6N6P.

I see Russian knobs =)Full tube consruction. 6C5S rectifier, ECL85 / 0B2 voltage regulator and line level amplifier with 6N2P-EV and 6N6P.
I see Russian knobs =)
All tubes, knobs and some capacitors are NOS Soviet.
My first preamp project.
ECC83/E88CCtubes at this point in time.
I have russian 6n2p-EV/6n6p too.
separate tone adjust, balance, bass output level adjust, program selector and mastervolume pot.
Yes. amplifier has two sets of outputs. Full frequency and the other is 40hz 18db/octave low-bass filter,with level adjust.
back row is the operating voltage rectifier and regulator.
5U4S/ECL85/0B2 from artosalo.
And my third power amp.
6F12P cathodyne driver/KT77 pentode connected PP powerstage. And GZ34 rectifiers.
