Good morning everyone I have this amplifier in the workshop without output mosfet and without source mosfet any idea which mosfet uses this amplifier for both sections
Good morning Perry, sorry for the image quality is what I have at the moment the camera still does not arrive and well I discovered that it is in equal protection raise Q101 next to R101 and pin 4 of the tl494 fell to 0 volts I can not find that I can be pulling on the base of that transistor. I told you that I also changed the lm339 but nothing remains the same in protection.

Does the output stage look similar to the one in the following amp:

ok I understand but the mosfet SSP45N20A are discontinued you know a good replacement for them and you think that at the source I can use irf3205. Of course after solving because it is protecting
If that's a yes, the IRFB31N20D should work for the output FETs.
The IRF3205s will work in the PS.
