Supro 1622RT TremoVerb Hum Problem

[Daniel S]

Well, I ordered from Tube Depot: a matched set of EHX 6973's, a matched quad of JJ Gold Pin 12AX7's and a Mullard 12AT7 I went ahead and paid the extra few bucks to have them test for Low Noise & Microphonics, and Balanced Triodes. I don't know if they actually do that, or just have trained squirrels knock tubes into a shipping box. I guess I'll find out in a few days. Wish me luck.

The Supro amp hum has been solved!! WOOOO HOOOOOooo!!!

It now has a "normal" very faint hum that does not change when any knob is turned or volume maxed. Just played my G&L Legacy and all I hear now is the guitar!!

I'm so thrilled. Thanks to everyone who chimed in on isolating this.
