Some BlackCat amps were marketed a little differently to fool the FCC (We all know how stupid they are right?) Look out on the schematic page and the JB-12 using a 6L6 type (7581A) tube was sold as a

I looked at the pictures of the amp. If it is unused, how did the screws on the right side get chewed up? If it is unused, why did the previous owner use magic marker to locate the input, output, ALC

I have to agree with Carl as to the price. $45.00 ea or 2 for $85.00! If you have a situation that you are damaging the seal due to poor cooling, they could be worth the price. Otherwise the usual $5
