[Hallicrafters] HT-32 hum

[psturdivant n1ps]

I have a HT-32 that has had an issue that I have put off.  It xmits some
noticeable hum when transmitting in DSB (AM) mode,  I have had enough
complaints about the hum....not very much...but it can be heard.

The hum appears with NO mike connected or with it in.

I'd like some opinions on the cause of the hum for anyone that has either a
32 or a 37.  It could possibly be the filter caps.  I have not looked at the
B+ or HV lines with a scope as yet and the previous owner replaced the
rectiflyers with solid state.
