Here is the latest - the unit is functionally working. Radio pulls in stations, phonograph works - plays records with sound using rebuilt cartridge. Not much hum when playing records. However, when my wife or my son touch any metal part of the turntable while in phono mode - they get a pretty good zap (and hum). For some reason, I don't feel it like they do, but when I measure AC volts between the turntable and ground I get 118 volts. If I swap the plug polarity using an adapter, the unit still functions but the voltage between the turntable and ground drops to about 10 volts. As part of the restoration, I replaced the original power cord with a 2 wire polarized plug cord. The unit is wired with the hot lead from the plug going to the switch. The C18, C27 and C27 capacitors are new. The R6 120K resistor is good. The ground wire from the tonearm to the case is in place. Measuring resistance between B- and the case gets 120K ohms. Is this normal? Should I swap the plug wires? What else might cause this?
