Default Re: Elizabethan LZ-29. Rectifier.

I've checked the circuit and there is no mains dropper. Do you mean the smoothing resistor R28 500R? If this is overheating then a possible cause is the smoothing capacitor C22 being electrically leaky.

Wire wound resistors do get hot. Has the HT voltage dropped?

Personally I'd have fitted a new bridge rectifier whose performance I could be sure of.
