I had a friend bring me this amp recently because the tubes were red-plating. It turned out to just be a bad solder joint where the cathode resistors went to ground. Thank goodness it was an easy fix because I could find almost no info on this amp.
Nice sounding amp. Another loud 45 watt amp. Nicely built.
I took a few shots of it, including some gut shots. It's pcb so it's not really anything I should have to worry about someone copying the design, etc. I am going to post a few shots of the amp. If this is over-stepping the guidelines, please remove.
I took a few measurements, etc. while I had it for servicing purposes only. Dropping string voltages, Original cathode resistance values, tube types, etc. I am not going to post any of those right now, but if someone needs them to troubleshoot a problem, I can PM them to you.

Re: VHT Pitbull 45 photos
The layout is a bit unorganized but I'm happy to see a two layer board with plated through-hole vias. These are much stronger than single-sided boards that Fender and other cheap companies insist on using (pads and traces don't peel off the board so easily). You do have to be careful because the high AC voltages will crosstalk from top to bottom, but I'm sure they know that.
I've never heard one but I'll agree it looks nicely built and is relatively compact for a 45W amp.
