I'm starting a re-cap on this Philco 39-116. First I tested all the tubes. The #80 rectifier is dead. Filaments are open. Then I noticed that two (2) SK3081 diodes are installed with the cathodes soldered to pin 4 of the 80 and the anodes, one soldered to pin 2 and the other soldered to pin 3 of the 80. Is this an attempt to bypass the 80 rectifier?

It's on a scale of how bad is it compared to... Naphtha, chlorine bleach, mek, and lacquer thinner it's odorless.Radioroslyn — 10:26 AM

Yeah, always wondered why they call them spirits "odorless". It sure enough smell like a gas station.morzh — 10:10 AM
