Philco 46-1209 Code 121
#25

I was able to work on things a bit today. PHEW! Hopefully I will find a better way to do this for next time. I'm sure my blood pressure was a bit high today. I got the potting out of the bakelite block and recapped with the safety caps, and replaced the 33k resistor and 240 pf cap feeding #3 on the 7F8 tube and also replaced a few other resistors that tested out of spec. I did find one suspicious resistor, #57 mixer plate decoupling. The schematics call for a 47K ohm (or a 4.7K depending on model) and I had one that had a green paper wrapper that said 60M, but the color code lead me to believe that it was a 60K. I replaced it with the 47K. After carefully reassembling everything I powered up and everything looked okay. I seem to get more stations now than before but I still have to have the volume turned up considerably. If I hold the antenna while tuning I get A LOT more stations at what seems to be a normal volume, but still not much below 900kHz (buzz @800 kHz) Do I need to do an alignment now?
