Silkscreen is gone in that area due to corrosion .I can see a black band in the center of the resistor.I install a 10ohm in there for test and amp powers up ok.I get good audio on all channel but Q32/33 heats up fast.Is that normal for this amp?
This is a zero ohm resistor which I believe is to connect spkr and pwr GND's. To confirm measure with an ohmmeter from spkr to pwr GND and if you read 10 ohms my assumption is correct.You will want to replace 10 ohm with 0 ohm resistor, but for testing purposes leave it in.
This is incorrect. the 0 ohm resistor I'm thinking of is R73. R36 should be an 11kohm 1/8w 1% resistor.
Q32/33 may be the +/- 15 volt regulated supply, which tend to run hot. Once they are mounted to chassis with a pressure bar they will be fine.
Q32/33 are in fact the regulators and as I said they do get hot but once the are clamped done in chassis they will be fine.
I will check schematics tomorrow and get back to you.
There are two 1N4148's attached to Pin 3,to be sure I would need the locator number for diodes.
The diodes are most likely D6 and D9-1N4148's connected to Pin 3 of U2-TL494. To determine check with ohmmeter from anodes to Pin 3.These typically don't fail.
I don't have a schematic handy. Are the color bands on R36 unreadable? Is this resistor connected to Pin 1 by any chance?
