Recordio Hum Radio

Hello,

Awhile back I purchased a Recordio 6b30. I have had all the capacitors replaced, and all the tubes except for the rectifier. I was told it was okay. However, there is still a hum that is pretty loud. It is especially deafening when on "radio" mode. Could it be anything else?

Thanks!

. . . wondering if perhaps polarity is off on one or more of the new cap connections? In any case, this type of issue would be best directed to this forum, which I personally have found very helpful for radio/electronic issues: http://www.antiqueradios.com/forums/index.php

Good luck!

??????

Anyway, still sounds exactly like a bad filter capacitor.

Do you mean the rectifier?
