Default Re: Hacker Sovereign 11

Here is a simulation of a Hacker audio amp with the DC voltages.
It is the A205, that is the schematics I did find.
I did some simplification, omitted the Vbe generator for the final stage, just used a simple resistor and adjusted it for about 2.8mA idle current.
Also assumed 18V supply voltage (2x 9V?)
Also left out some of the tone control circuits.
Audio gain is about 60dB.
Hopefully it is similar to your amp and it helps you.

Regards, Peter
