MOSFET Amplifier IRFP240/IRFP9240

PSU for MOSFET Amplifier

Apex, Could you send the schema and PCB of power?
This PSU was used in time when I building this mosfet amplifier. There is PSU, DC and overload cut-out protect for each channel and soft-start for toroidal transformer. This circuit can be used with any amplifier.

PA Protect can be used with Hi-Fi amps also. For silent operation 47R/5W do not stafed, and fan do not work on low speed, when heatsink temperature is over 60deg it will turn on to high speed, and even without fan when heatsink is over 90deg protect will cut-out speakers anyway.
