I have a Super Sonic 112 that I tend to only play at really low volume (I know that's weird and I have a DRRI, but I love the sound of the SS - the clean is very different than the DRRI and the burn is really nice). Anyways, at low volume the amp noise is very quiet until I turn the reverb up - then I get a pretty loud hum (it gets louder as I turn up the reverb). I really like the reverb on this amp, but it is just too noisy. I've heard about low noise tubes - would using those in the 2 reverb tube positions help? What are some good low noise tubes? Any other ideas? I've tried a lot of tubes in those positions (even the tubes from my silver-face tube reverb which is dead quiet) and it's always noisy.

Seems that the problem is not tube related as evidenced by your trying different tubes that are quiet in other amps. Any good tube will not hum, that isn't what low noise tubes are about. Likely one or both of the reverb cables, or their connection to the board is the problem. The reverb circuit, cables and tank should be inspected. Make sure that the cables are plugged in to the proper jacks, if they are reversed that could also cause hum.
