Zenith H725
#6

Ed:
I'm not sure how much work you want to put into this but you could convert the set from being a hot chassis to a floating chassis set. Someone from the U.K on the A.R.F mentioned that they like to do this with British radios over there, since as he said "getting shocked by 240 volts hurts a lot". IN fact I was looking over mt Bush DAC 90A and I recon it would be easy to do it with that set since most of the caps are mounted on a terminal board. The H725 might be more difficult, I don't know, but then again you could just copy a floating chassis set, like a Philco FM model.

Arran
