Today I continued some work on the chassis by replacing items 16 and 15, 47K ohm resistors, and item 37 a 33K ohm resistor. In the process I found an added resistor, a 27 ohm between the grid of the 7J7 Mixer/Oscillator tube and the band switch which is not on the parts list or the under-chassis parts illustration. This is likely a modification to reduce the possibility of spurious high frequency oscillation. Neither the Ryder information nor the Philco Service Bulletin 321 show that added resistor. I need to do some further checking to see if I can find information on this. It would be interesting to see if my suspicions are correct.

I hope to get the remaining capacitors I ordered so I can finish up the chassis work.
