41-287 No voltage from secondary of transformer
#3

Hello Ron, Thanks for the fast response. To answer your question, I measure 532 vac across the plates of the 84 rectifier tube. The schematic shows 265 vdc across the 12uf ecap. Having replaced it with 22uf I show 360vdc and across the 16uf ecap the schematic indicates 180vdc. With the replacement 22uf ecap item 27A shows neg 56. Also you asked about the Candohm resistor, yes, I removed the entire piece and replaced it with separate 5 w ceramics of 15, 33 and 150 ohms. I also noticed an error when I changed the 12uf ecap - I had the negetive side to ground rather than the center tap of the transformer. So, no sound no smoke just filament and indicator lights. JEP

Absolutely no one is going to reverse engineer that circuit. Even the iron core is missing.RodB — 10:37 AM
