Tube Works 921 Reverb

I have a hum in my rack unit. I always thought it came from my Emmons single wound pickup. However, recently I've been fooling around with a Goodrich Super Bro and happened to by pass the reverb. Low and behold, the hum disappeared! I assume there are tubes in the reverb and could this be the cause of the problem? Would bad tubes cause the hum? I like the reverb from Tube Works but sure could get along without the hum. PLease advise.
Uff-Da!

I have a RT-921 tube works reverb and have problums with hum also, the hum is in the wart power supply...you have to keep moveing the power supply untill you get most of it out...i have fell to get all the hum completely out, but mabe someone out there will be able to tell us how to get all the hum out.
