Lots of great advice, thanks everyone. One last thing, where can you buy a tube? Would GC have that kind of thing or should I go onto this thing called the "Internt" to buy one?

Most decent Shops will if you need fast.
Are you using a 12ay7 (my favorite) in the V1 (first position)?

Look in the parts emporium for tubes long term. I'm going to suggest taking it to a tech. It's worth it. Have them show you how remove and reinsert the tubes. It's not tough, but you don't want to break anything.

Honestly, rotate in a circular motion? Wow.

If you tap on each pre-amp tube while the amp is running, a bad tube will let you know right away when you tap on it using a wooden chop stick or pencil. Tap each tube with the volume on 3-4, it will be easy to find the bad tube as it will scratch and make sounds.

Also try using a 5751 tube in V1, it will raise the gain from 44 to 70% by a simple tube swap. It's like adding an early break-up at lower volumes. To get that ZZ Top tone use the 5751 in V1. You can safely use these tubes to raise/lower the gain.

Rotate, not twist! Do we need a youtube video to demonstrate this?!

I was trying to identify the tube with a wood spoon, but none of them so much as peeped at me. In fact I'm unable to reproduce the issue at all. Go figure. Could my fussing with the tubes squared it away? Is it an issue that I should expect to see resurface?

Thanks
