Hi, I am crurrently trying to restore an old fisher X100-C. it had been previously restored by changing a few capacitors.
I am strugling with weird voltages right at the begining of the crircuit.
the secondaries of the ransformer are 6,1V and 158V AC. Voltage gets rectified and raised by a two diode circuit and shoud raise it to 430V however I am reading 960 V. Does anyone have any suggestions?
thanks

Thanks for the reply Jon, I fear I didn't explain myself well. I had a new transformer made for this amp and it's secondary outputs are 6,1V and 158V .
on the schematic , after CR1 I should see 430V and after R65 360V however in my case I have extremely high voltages there: 960V after CR1and i don't understand why

Don't worry, it happens all the time, until manufacturer make a VOM which interpretes itself what one want to measure.
That would be quite unusable
I'm looking for the big knob, the brass end is missing on my X100-c. Any adresses for these?
