heres a weird hybrid one -
R132 was (literally) burnt out - i replaced it and the amp is working fine, but im trying to understand what would make that resistor fry -
i checked the diodes in the bridge that feed it and they seem fine - where does the V- that its filtering/providing even go? i assume to the opamps for a +/-15V swing but i cant quite find evidence of that on the schematic -
what could make that particular resistor burn up? its in a lowish voltage part of the amp so im a bit confused.
note: R132 is in the lower right part of the schematic - off the transformer, through the lower voltage bridge -
