A humble small EL84 triode connected PP, 5 watts. The voltage amplifier and cathodyne tube is the 6211. The power tubes I use are actually russian 6P14P-EV. Fixed bias.
Loooks elegant and really well-made. i like the "low" style. Can we have a loo of the inside?

Very nice

OK, but I'm not particularly proud of the internals on this one... ^^
The relays on the output are speaker bypasses, to use two amps with one pair of speakers.

hello ,
me little build " Signal Tracer " for problèm to old TSF and amplificator Hifi & Guitare ...
the build is upgrad later for multivibrator +/- 600 Hz

Mark II, much improved chassis and board, big improvement in sound as well. Double coils on c-core transformer for outputs, 110 VA power transformer, CRCRC PSU filter. Very dynamic and very quiet. At its best with 97dB/W plus speakers.

Absolutely beautiful workmanship, Vincent77 and Professor.
I agree! Your build is very neat, Vuncent
I this the Coffin diagram?
Beautiful construction, how it sound? I this the Coffin direct coupled amp that originally come with 6C41?
Best Regards
My newest SET: a 6C45-PI driving half of a 6C33C. Output transformers are One Electron UBT-1.

Thank you for the compliment! It sounds quite nice. Clean and clear in the mids and highs with strong, articulate bass.
I should probably note that I am running the transformers so that I get an impedance ratio of 800:8. This sounded better than the other option of 1.6k:8. The two stages are RC-coupled through a Russian FT-3 teflon capacitor, so only the tube choices are similar to coffin's amp.

^Really nice restoration.
It was a Philips EL6420 PA amplifier.
To good use in the Hi-Fi made profound work.
Here is his new scheme:
