Hey, I recently purchased a emud model t7 radio. I have a problem with the power supply and cant quite figure it out without a roadmap. any help would be appreciated. I had the radio playing fine and all of the sudden just a hum. I have replaced the 3 section filter cap, but now am getting just around 147 volts on the b-plus where before the hum problem I was getting around 300 volts. any thoughts? thanks Mike :scratch2:

Sams 473-8 - don't think I have it. I see that it's listed at radiomuseum.org - send me an email and I'll send the schematic. tbavis(at)rochester(dot)rr(dot)com

Thank's Tom for the reply and offer, I talked to my friend today and he had it in his sams. I went by after work and picked it up.Upon further investigation this evening I found that the output transformer was toasted! I hope I can find something to replace it with. :tears:

I have one from a Norelco radio that might fit - it's for an EL84 - what are the mounting hole dimensions?
