Tom:
The hot cap has two likely possibilities: either the cap is shorted
internally (an ohmeter check will show leakage) or you have bad diode(s) so
AC is being applied to the cap. An ohmeter will show the diodes as bad.
a backward diode will supply AC to the cap, also
No, it won't.
oops. right. 1 diode backwards in a full wave (not a bridge) rectifier
would short the xfrmr.
It will however supply the wrong polarity of DC, which could indeed
cause these symptoms.
I would think some other semiconductors might be running rather hot too
if that were the case.
