Philco 60 Higher Frequencies
#15

I have checked for shorted tuning condenser plates, replaced e caps, replace caps in the tar blocks and replaced all out of tolerance resistors. I even replaced that cap in the oscillator coil with a new 110pf silver mica. I have done an alignment using a generator at 460. I got a fair amount of gain on trimmer under the 78 tube. The other three IF trimmers were very touchy but I think I have them aligned. By touchy I mean less than a 1/8 of a turn before loosing the signal. I even took out the antenna coil so I could replace the grid cap wire. That outer winding did not look like the outer winding I have been messing with on the oscillator coil. It is wound with a non enamel wire with cloth cover. Looks about #24 wire or less. I didn't know if that was normal or not as I nothing to compare with. I saw a bandersontv video where he showed both coils and his antenna coil looked pretty much like the oscillator coil. So now I wonder if that winding is the problem. I don't have a picture of that coil but if it would help I will take it out and take a picture.
