speaking of Don Juan Matus's old stash ...... I've just found these in corner of my garage

these are smaller than those I'm expecting 'morrow, but still doable for making 15W amp

Since you metioned germanium transistors.. I just remembered my first (failed) amplifier with Ac187-Ac-188 pair...

Find this in the archeology fossils category. Amp inside of turntable.

small signal ones are not interesting , except if you're fan of guitar effects

You mean amp: Jfets + SIC mosfets + Germanium power stage à la Stanley Kubrick ?
Proper build class A Ge line stage why not can surprise Hendrix ?

Since you metioned germanium transistors..

Still alive today in hybrid silicon - germanium SMD components

no SIC/SIT in that special schematic

there is no place for two superfunny parts in one gadget , final concoction would suffer in performance

besides , I'm still young , read- not smart enough to fight two Windmills at once

when I grow a beard , Helmet, Sword, and Rosinante , I'll try

~ 400 articles do play with SIC Mosfets and Korg Triode a lot.
The Knight Ge amplifier AB class was build in Russia..well in pure A frequently 15Watt's is plenty

ROHMs - all in range of 8V for Ugs

too much hassle

Designs list is a gigantic, we see use of Silicon Carbide Mosfets start at 2012
