As I was walking in Taos,NM last weekend looking for flea market type stores I noticed an amp that looked just like an SVT on the porch of a second hand store and my heart started racing. I bought it for twenty dollars and took it back home knowing the least I'd need is a new set of tubes. I looked under the hood and noticed all connections looked fine except for the 2nd channel wire and that it was a b22x made in NJ. I bought a set of tubes from fliptops(which listed a quad set of 7027A's but only sent me a pair, not cool) and popped them in and it worked and sounded great with a guitar and bass. I can't seem to find any info on this amp and would like to know more about them. Given that there is an echo rocker switch and a tremolo and vibrato preamp section it's designed for a guitar but a bass sounds great too. I think it's a 50 watt amp. Anyone else have any input?
