Still working on the Technics SU-V9.
Opamps need changing as -54v went through -17v rail. I currently checking other components, so far seem good, but sure opamps would be fried
RC4558? supposed to be a directly replacement for AN6552
DC Servo ?? low noise cheap opamp in pre amp pcb
Voltage Comparator ( load impedance) ?? low noise cheap opamp
Tone Amplifier - something like OPA2134 there maybe
some thoughts
TI NE5532
TL072?

An externally hosted image should be here but it was not working when we last tested it.
