Philco 38-116 Question More Questions
#27

More digging in and remeasuring the Mag switch and yes, it works nicely when monitoring it and takes each leg coming off of it and to ground when the switch is turned. Great! Problem is that when I measure between the two legs of the switch, they are always shorted together, regardless of the switch position on the front. Leads me to believe that that elusive and yet to be discovered switch labeled 97 on the schematic is not opening! I think!Icon_crazy I may have to find that puppy but somewhat clueless as to where it might be. Perhaps on the back side of the tuning dial? But why? Disable the mag tuning somehow when using the "speed dial" feature. Still clueless in Sedona but trying. Am I safe to assume (scary) that switch needs to open for the mag tuning to work? PS: Ron, lovely job on the schematic, makes things much easier to review what is going on.
