The continuity checks good to ground from pin 4 of L2. All tube voltages look good as well. I have not tried adjusting any of the trimmer capacitors, since that can really put things out of alignment real quick. I did find that one of the ceramic capacitors is reading 53 picofarads, when it should be 3.3 picofarads. It goes from terminal 2 (FM antenna) to the trimmer capacitor on L1. I currently do not have any replacements that size, but will eventually replace it. I have also noticed that if the jumper from pin 4 to pin 2 on L2 is just a short wire, FM still doesn't receive. The length of wire seems to be acting like an antenna, which makes me think the problem is between L2 and the antenna terminals. I may have to start removing one end of resistors and capacitors in this area and verifying their value against the schematic. I'll get back with more info once I do additional troubleshooting. Thanks or your help,
Rick
