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.

Triode connected PP EL84 can sound very good from experience. Glad to hear I am not the only using fixed bias with EL84.. Nice classic uncluttered look!

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.

Absolutely beautiful workmanship, Vincent77 and Professor.

I really like the wood burning that you did for the face plate of your amp. That adds a very nice touch to the appearance. Well done!

hello ,

me little build " Signal Tracer " for problèm to old TSF and amplificator Hifi & Guitare ...

the build is upgrad later for multivibrator +/- 600 Hz

My first EL84 triode connected single ended prototype. Chassis was a mission to build but turned out well.

 

[Jnouw]

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.

I agree! Your build is very neat, Vuncent

My newest SET: a 6C45-PI driving half of a 6C33C. Output transformers are One Electron UBT-1.

I this the Coffin diagram?

Beautiful construction, how it sound? I this the Coffin direct coupled amp that originally come with 6C41?
Best Regards

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:

 

[Jnouw]

Very beautiful restoration, and quite a rare unit. Interesting to see the separate windings for feedback. Nicely done.

This is my new game. A KT120 pp amp driven by a single D3a in pure A class, no NFB, 28W triode connected and 55W ultra linear
