Okay...guess I didn't know how to deal with pics I had uploaded before.
ALOT of my sets WILL fall into this category. EVERYTHING I have is pretty much "portable"...but most are actually battery as well
I don't even own a tube set yet, and when I do...it will likely be something famous (or infamous?) for being a very SMALL tube set (appreciate any leads or ideas on a VERY small tube set by-the-way)
