46-480 Power Transformer Vibrates
#4

I went back to an old basic first with these Loctal tubes. I cleaned all the pins again. I'm picking up a few AM stations but weak. If I remember, I need the copper wire loop antenna out of the cabinet to make this AM work. Please correct me if I'm wrong.

I get lousy FM here but I do pick up a few stations. I'm getting nothing on the FM band using my dipole in the attic.

Transformer is running warm when powered up now and tubes installed. But all voltages are solid and steady. I did re-secure the transformer to the chassis and that vibration in minimal now. There is no real hum as was explained to me but there is a static and crackly sound coming from the set.

The Ecaps test good isolated and I could throw new ones in. But I don't believe that's my problem now. Have to agree with Jerry. "But what do I know".

I also cleaned the bandswitch again. No change so still pluggin' away.

Please let me know on that copper rod loop antenna that's in the cabinet. I don't have it and if my memory serves me well at all any more, I think I need it for the AM.
