Pentode driver, and a resistor between anodes, choose for taste. That's it.
pyramid drive?
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.
