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?
