I've rebuilt the amp replacing all electrolytics and tubular caps. I found a couple of 5Z4's in my stash that I didn't know I had, then proceeded to track down a bunch of intermittent issues. Most of the grounding tabs are on the tube sockets that are riveted to the chassis. The top of the chassis was painted before the tube sockets were riveted in. I had a lot of loose rivets! I wound up soldering all of the tube sockets to the chassis to eliminate the problem. Except for a couple of microphonic tubes , it seems to work good.
The amp has found its home on the top of an old Allen organ speaker in my 13 year old grandson's bedroom. He's learning to play bass guitar and the amp and speaker work quite nicely for that (of course, none of the effects). He's really geeked to have a tube amp for his bass and the 15" driver in the speaker really shakes the room! He's going to have to keep the volume down.
