Wow, What a web site. I've picked up a lot of info but now I have a Model 620 that is kicking my rear. A year ago I recapped the set and it was working fine. It was put away until I could get to the cabinet and now it has failed. No audio was being heard until I touched the grid of the IF tube. I suspected the IF coil but it has good continuity. All tube voltages appear good but if I touch the plate of the 6A7 Det/Osc with a meter probe the radio plays fine. I hope that all of the Philco knowledge out there can point me in the right direction. Thanks to this web site I was able to stop the squeal by rounding up four tube shields that the radio did not come with. Thanks in advance for the help that I know will come.
