Thanks for the tip, actually they are intended for PP monoblock but I'm still looking for a good schema to base on. I already have the OPT and Power Trafo with 1kv B+.
Pentode driver, and a resistor between anodes, choose for taste. That's it.

pyramid drive?
pyramid drive?
Pyramid is PP. I used the same principle in Gubernator - 13 and Gubernator - 71 amps. Much simpler, less power, but SE amp with 813 or GK-71 consumes much more than PP Pyramid with GU-50 tubes designed for mobile equipment.
Sodacose: very nice.
Here's my attempt at a tube build. I's a Muffsy BSTRD. I'm not into tubes, but I had to build the bstrd as I have built all the muffsy phono stages
I planned to run it with bare pcb for testing, then I found an old dtv decoder that I could use for chassis. Here's the result. It's not a looker, but it sounds interesting.

Thank you! That BSTRD looks like a nice little circuit, too. Nice job on the scavenged case
Here is my 12AX7/6SL7/6SN7/6AS7G pp triode amplifier. about 12w/ch.
With tone controls.
Not fully finished yet. (mark lamps and wood side panels needed)
And there is my second amplifier set. Separate pre /power amp.
Pre has 6N2P/6N6P with tone controls + 40hz 18db/oct sub out. And tube regulated power supply.
power amp has 6F12P/KT88 80w/ch
And the last is shown in the background in monoamp, that drives the subs.
Same type... 6F12P/KT88
in the foreground is shown 6as7g test bench
a big thank for the advice Artosalo

An externally hosted image should be here but it was not working when we last tested it.

Is it an OTL amplifier?

EL 84 monoblocks - Eico and Fisher inspired, but more attention applied to th PSU.
Push pull? What is the power output?
Is it an OTL amplifier?
No. OPT:s are inside.
