I have this precision power pcx-1500 and it turns on and works but not like it should. I opened it and found 2 burnt resistors behind the inputs for the rca sheilds & i have some replacements. But the problem is that as soon as i apply the remote voltage to power on there is a resistor getting extremely hot immediately, (no speakers or rca hooked up) its the one right between the 2 coils, what is it for & how do i fix this? Could it just be out of tolerance? I cant accurately measure it while its installed, meter fluctuates. For the rca sheilds I tried 47ohm & 47kohm & left it open but no change.
