Philco 38-116 Question More Questions
#24

Ron, thanks for jumping in. The mag tuning switch is fairly simple, turned clockwise (I believe) turns on the mag tuning and indeed turns on the lights (flood). That would not change the working of the on/off other than giving you a wrong light turn on for the flood if the four wires were wired wrong. One pair to one side with the 6V on that side and going also to the tuning light. Keeps that one on all the time. Moving the switch to the mag on position, ties two other wires to light the "flood lights". The other two wires going to the switch go to a small rotary switch that will take the two wires from going no where to grounding them. Even if reversed I don't see how that would make any differences. Yes that aspect of the switch works as indicated on the schematic.
As indicated earlier, following the alignment as I think I understand it, if measuring the output on the speaker with a VOM, I see no change in following the procedure for alignment. I can see a very small change on the plates of the the 6J5 output tubes from the circuit. They seem to do something but nothing on measuring a modulated signal to the speaker. I'm probably doing something wrong but trying to follow the directions.
A lot of help here for those of us electronically challenged.
