Default Re: Murphy A104

I restored one of these this summer and used 650v caps throughout without any problems, I suspect that they had a lot of caps in stock and just used them up. The tone correction caps across the output transformer should be 1000v but I prefer to take them from anode to ground, then their life is less onerous, and 650v seem to be fine then.
The optical system is a fine piece of work when set up properly, for a 2w bulb its surprisingly bright. If the silvering on the mirror has gone, try a piece of aluminum foil wrapped round it, shiny side out.
