8) That's neat. The radio is a PT-28, a neat little 5-tube radio. I did adjust the IF transformer slugs ( I assume that's the two little screws inside the metal housing looking down from the top). I noticed that the station at the low frequency (which is weak even under good conditions) did get louder. Then I adjusted one of the screws on the tuning condenser (again, assuming you are talking about the two screws side by side atop the tuning blades). The station got a little louder. But I am missing one of the tuning screws. I tried using one from another Philco radio I am working on, but it did not seem to fit. It was too tight and I stopped trying before I damaged something. When I tuned the radio to a better station, it came in pretty loud, but the voices sound garbled and there seemed to be a lot of vibration in the speaker.
Any more suggestions about the alignment (missing screw) and possible symptoms of garbled reception? The caps have all been replaced and I think the tubes are OK. I did not change any resistors.
Thanks again.
