Re: Elizabethan LZ-29. Rectifier.
I'd agree with Graham and HB. Fitting a N.O.S. contact cooled(or any other type ) rectifier is, IMHO, asking for trouble. As others have said, it's not difficult to fit a modern silicon bridge rectifier. The two wires from the transformer secondary go to the terminals marked either 'AC' or with the '~' symbol. The Negative terminal on the new rectifier (marked - ) goes to chassis, and the Positive (+ ) goes to the smoothing capacitor via a series resistor. The Smoothing Capacitor should be checked and, if necessary, replaced.
