Help with a squeal, Please.

Well, my Holidays ended and time was limited but we did finish the amp while I was in Revelstoke. My brother-in-law got to take the amp home, and was told I can always take it back to tweak anything later, after he's had it for a little bit. He was instructed to leave the NFB switch in it's current position, and I'll figure out what to do with it later. It is hidden under the chassis by the tubes anyways, so he won't be messing with it. The hole in the faceplate became a second input for the T-Rex Channel. Hey, why not? Unfortunately, it's still labeled MV with numbers around it, but I can either try to get a custom faceplate made, or come up with a good acronym for MV that fits.
Here are some pics of the final amp:
The wood on the front is Purpleheart. Something we've done on every amp I've built so far.
