Philco Model 66 Repair
#1

This is the oldest radio I've worked on so far, so it's a great set to learn on. The radio hummed when I got it and the volume control did not adjust it. I changed the electrolytic caps and all the paper caps, and I still get a hum, but the volume control now does work. I then decided to gut out and refill the bakelite blocks, which this set has four of. One problem I'm having is with the middle switch is siezed. It suppose to switch from AM to shortwave, and perhaps police as well. It does not move I have tried everything. I saturated it with 3 in 1 oil and tried working it in. Perhaps someone glued it to the AM spot, but it is not loosening. Another thing to considedr is the oscillator transformer, which I hear these sets are notorious for malfunctioning. When I use my ohmmeter, gound the black wire to chassis and test each lug, I'm coming up with 11.3 k resistance on each lug. Is that a good indicator that it's okay? I have a few 100 uuf caps coming in the mail to satisfy the last bakelite block, so there is no more tests I can do untill they arrive in the mail later this week. Any suggestions?? Much appreciated.
