Thanks again for the replies.

I solved the 120V on the chassis mystery - the new cord I installed wasn't
polarized after all. It has a white stripe on it (black cable) and one of
the tips appeared bigger than the other, but it would fit in the socket
either way. I installed an actual polarized cord and the chassis is AC free.

Hopefully I'll get to the caps soon. I'll keep you posted.

Thanks

When in doubt, use 33uF or so, @450V (22uF is OK for a start. If the
hum reduces but does not go away altogether, then go up). Otherwise,
200uF @20V or so for LV stuff.

Bridge: Voltage in X 1.4142 = voltage out.
Single diode: Voltage in .7071 = voltage out.

Keep that in mind.
