It appears there is a short between the primary and secondary of the SW antenna transformer, but I have not located it. Rider Vol. 6-37 thru 39 shows 53 ohm secondary, but mine uses different transformer part numbers than Rider shows. Anyone have detailed coil info on Antenna trans #38-6915, RF trans #38-6916, and Oscillator trans #38-6917? (Some Rider Philco info has coil alyout and terminal orientation, but not for the 650.) These are the ones installed in my unit. I aligned the radio and it does track very well - just very weak reception.
