Below are several interesting circuits using the 801,
808, 811, 826, 838, 4d32, 2A3, etc. in what are mostly
single ended class A2 audio amplifiers. Some of the
circuitry may have uses in AM modulators.

"He(Mr Kouichi(Nobu) Shishido) used to be use some
technic of inter stage transfomer.
his many amplifier are almost same technic of  inter
stage  transfomer. he  invented
call it's  inverse phase connection under interstage
transfomer amplifier.there are
almost use for Transmitter valves Amplifier as Audio
Hi End Amplifier.some one call
it's Positive Grid Amplifier.just I will  introducing
you some  circuit  diagram  of
shishido's amplifiers here."
