Does anyone have a repair manual for this amp? Or know the layout?

First time owning and working on a 5 channel amp. The sub channel power supply if burnt q35 through q38. The gate resistors are damaged also. They are marked 470. 47 ohms correct?

Testing irf9640 P channel FET red probe drain black probe source I'm reading .819 on one fet and .732 on 2 other fets. Are they bad?

Testing in circuit or out? I only asked because other components can alter your reading.

Out, and reverse procedure of testing an n channel.

470 = 47 ohms (4, 7, and 0x10 multiplier).

The probe orientation is reversed when checking P-channel FETs.

Yes, i got the test procedure from your website. Are my readings from the drain and source ok or do you think they are defective?

resistors r30 marked 102=1kohm. Value is .431ohms so its bad. How do I determine the watt rating. One side is connected to the source of the PS FETs and amp ground terminal. I cannot trace the other side

Is that .431k ohms? Or .431 ohms? The latter would suggest its bad or something in parallel is shorted.

413.7 ohms. I was in a hurry typing, sorry. There is a another resistor in the circuit r40 which reads .959kohms so I'm thinking its just the r30 resistor thats bad. Also the power supply FETs are removed (this is the sub channel).

Remove it and measure out of the circuit.
