Ok, I found an Ampeg SVT350 head and a matching 4x10+horn cab for about $600-$700 at a local shop. It is in good shape aside from the plastic sliders missing off of a few of the EQ sliders (they can still be manipulated, just no little plastic tips). I know little about Ampeg gear. Is this a good deal? Is this a tube or solid state amp? What should I look for when I go back later and try it out in more detail? Thanks in advance for any assistance!
