too much power to faceplate?

[Tom Bavis]

An ohmmeter won't always show leakage - it may only appear with higher voltage. Capacitors this old are suspect though - best not to plug it in until it's fixed.

Got a model number? We may be able to scare up a circuit diagram and point you to the problem part(s).

Zenith Mt1958, The Photofact packet i have has it and the schematic under Zenith Chassis 9H21LZ1/Z2, 3K01/01Z/01Z1/02. The 10 electrolytics I already replaced as well as a few paper, and black plastic tube ones with orange dips including the one the is before the transformer in the circuit. Aside from the changer motor, all circuits are powered by the other side of the transformer. There is one capacitor and resistor that connect the power to chassis ground as in the schematic. (.022MFD at 600V and 1 meg resistor) The is about 1.2 meg ohm resistance between the respective power prong and chassis.
The main transformer has two secondary's according to the schematic (Pri. 117VAC @.86A, Sec. 1 117VAC@ .19A DC , Sec. 2 6.3VAC @ 3.1A) I might be able to scan it if that would help at all.

OK, 0.022 uF is TOO BIG - current safety standards don't allow more than 0.7 mA leakage to chassis - this works out to 0.015 uF MAXIMUM. The 1 meg resistor is NOT a safety approved part, and an old cap is probably leaky. I would replace the cap with a .01 uF safety approved part (Y-capacitor with UL safety label) and eliminate the 1 meg resistor.

I just found the schematic for the amp... even worse! C19 is a .047 uF capacitor from line to ground. I suppose they expected you to just flip the plug over if you get a shock from the chassis - again, you MUST replace this with a smaller value, safety rated part - 0.01. C3 likewise is .047 uF, from line to the tonearm shield - reduce to 0.01.

It is possible (but unlikely) that the transformer has leakage to ground - you'd need an insulation resistance tester (I use my Sprague TO-4 cap checker) to measure it.

Ok, I have some safety caps on order. A couple of questions questions though:
1. What purpose does the resistor have? will it matter being absent from the circuit? (sorry, I'm a bit of an rookie when it comes to circuits still)
2. Would it be a good idea to get a 3 prong earth ground cord and ground the chassis?
