I'm trying to revive a PET 4016. I've found the voltage regulator schematics, but i cannot find the expected voltages IN to jumper J8 from the transformer.
connector from transformer to J8:
1 2 3 4 5 6 7 8 9
brn red blk red brn blk key blue blue
2 and 4 go through the filter capacitor.
what i measure:
1 to 5 = 18 vac
8 to 9 = 17 vac
3 to 2 or 3 to 4 = 0.5 vac
I think 2/3/4 should provide 5vac?
any help is appreciated.
