Im working on this receiver and it has been quite abused. The picture is of the amp board and the resistor that is circled in red I need some help with. It looks to me to be color coded brown-black-brown.
According to that it should be 100ohm. Both measure 1 kohm. is there anyone that could double check that for me. I don't know if there just that far off or if the color changed from heat or if the color code was wrong to begin with.
The unit seems to work except for a very quiet hum from the speakers. But when I check bias voltage I actually read 100 VOLTS! I checked it a couple times and both channels are 100 volt not 100mv. Im going to try and rebuild this board but these resistors have me baffled as to whats actually supposed to be there.
The huge white resistors I installed just to test because one of them was burned open. (put in 10 watt and original was 2 watt. this will be changed when I order parts). Im checking bias across the smaller .47 ohm resistors.
Any help is greatly appreciated.
Thanks
Justin
