Philco model 52-944
#6

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
