Problem with Monarch 8 Series 8000 amp

[saptemari]

Hi everyone!


Does anyone have any idea about where to find the Monarch STA-8002 MOS circuit? It may be very close to STA-13000 MOS.



Thank you very much!

And I think there were some similar amps named Zoffmusic. I can't find anything about them either

Outputs driven directly by the Vas. Really low performing design compared to what it could have been. Driving Mosfets is not a high impedance load for the Vas!

Thank you very much! Unhappily the circuit is different. It has an IC.

There was a chip designed specifically for driving and biasing mosfet output stages. I'm trying to remember the chip and manufacturer. I'll post if I can.
