I had one of these 1972 amps about 10 years ago (in LA) that I totally went through to overhaul, retubed it and it came with a flight case, that I sold for $800. The amp was free to me from a bass player who had 2 other SVTs that he wanted me to go through and get working right. Oh well, easy come easy go... LOL!
I bought a late 70's SVT head in Lima Peru where my wife is from about 15 years ago for 300 bucks, needed a cap job and tubes. Used it last night.
