philco pt2
#2

Hi Wally! I am sure a few others will chime in here. I don't know how much experience you have or what test equipment you have. Looks like an ac/dc radio. I would start by a couple of quick checks. First, since this is probably an ac/dc set, you will have to be very careful if you don't have an isolation transformer. One side of the chassis will be connected to the ac line. You could get a nasty shock. That aside, with the radio on and the underneath of the chassis accessible, a good place to start is to touch the volume control lugs with your meter probe tip and listen for a loud hum or static from the speaker. If you get a loud hum, then you have a live radio and you will have to go deeper into troubleshooting. If you don't get anything, check for B+ off the cathode of the rectifier tube. Should be 120-150 DC, chassis ground volts unless it uses a doubler, then it will be over 200v. I don't have a diagram handy on your radio, but these are a couple of quick checks you can make to get an idea of what is going on. There is a lot of knowledge in here, so am sure any of us can help you through this and get your radio playing again!
