Hi Audiofanatic, if I'm not wrong those resistors (3k3) connect to Drain IRF610 and it's serve as the loads for the IRF610. If mosfet's damage it's possible make resistor's overload and burn it. Just replace with new resistor, if it's burn again...replace those Fet's. It's cheap enough... What a Miguel doing this before?

I have a picture from Miguel that shows a shorted Zener, that makes it difficult to say if its ver0 or ver1.

one possibility could be,..... someone repaired ver1 with the circuit of ver0....


and caused some problems....

only a possibility

unfortunately I can for unknown reasons not upload the picture...

hi audiofanatic,

would you tell Miguel in Spanish to look for the Revision number on the board? compared to the service manual it should be ver1 and not ver0....

one resistor right and 12 Zener (one shorted)

I don't know about this particular board, but in general quite often besides running wires to replace the function of damaged/lost traces, adhesive-backed copper tape may work. It is commonly available on the auction sites. Just trim as needed with scissors.

Click the image to open in full size.
this is what is recorded in the PBC and the IRF9610 (Q5) has
soldier a zener and a resistor that is not on the circuit, nose if it is an improvement because they seem original components.
