Hi. Do you still an F-2507 driver board? I'm in Australia. There were different versions of the board so you need the right one. I have a BA-3000 with an incompatible un-needed board. My version has silver heatsink and bias transistor mounted on the board. I restored this board including all transistors (apart from bias transistor). Let me know if it's the one you're after. I don’t know how to price it. Cheers, Col
