Hi all - new to this great group and pretty inexpereinced with radios. Have two Philcos, a 37-620 and 40-190. The former was professionally repaired by a retired repairman (found it thrown out in the street!).
The 40-190 is in pretty good shape, except for some dings on cabinet, including a tiny bit of missing veneer. It is also missing the cardboard tube around the built in antenna. The unit does play both AM and "Police" bands, but there is a noticeable hum. The odd thing is that this comes and goes if I turn and/or tap the volume button. The shortwave stations similarly drop in and out, with pretty poor reception overall.
I have tested out all the tubes and they were ok when I last checked - I do own a tube tester. So: what is my next step(s)? Should I replace the capacitors? Does the volume pot need to be cleaned and or replaced? Anything else? Any advice appreciated. Thanks!
