Pioneer A-09 diamond-buffer non-NFB power amplifier circuit simulation

Use TINA-TI simulation PIONEER A-09 power part
* Super Linear Circuit (SLC) diamond type VAS
* Diamond buffer current booster (non-darlington)
* non global NFB

ps. use alternate transistors.

please show the harmonics

Hi, dear padamiecki
Did you mean THD ?
TINA-TI have not good function only a Fourier Series analysis .

This simulation my analysis data:
1W/8R, In=.16v Out=4Vp : THD=.0041% 1khz , .0043% 20khz
35w/8R, In=.95v Out=23.6Vp : THD=.27% 1khz , .27% 20khz
