Philco 645 Hum-m-m-m
#26

After much hit-or-miss alignment, I hit a combination that got the set back to the condition it was in a couple of days ago when I first managed to eliminate the hum. There was no hum with the set on the bench. Put it back in the cabinet, power on, and I get the same hum again--maybe a little less hum. Tried a few things. Moved the set around the room. Plugged it into the isolation transformer that I had been using. Took off the bottom dust shield which had aluminum strips on it. Went outside and swung a dead chicken over my head three times. But it still hums (the radio, not the chicken).

So, I'll leave it alone while I try to procure a reliable counter. When I'm ready to play the alignment game again, then I'll put it back on the bench to see if it still hums outside of the cabinet.
