Hi, I'm helping the family of a SK sell his equipment. I'm trying to find a fair market price for: Omni 545 & PS 255 Triton IV 540 and PS 252 Keyer KR50 They look to be in decent condition but I haven't given them a thorough going over yet. I know he used to disassemble stuff & needed help with the re-assembly... Thanks! Gary KA1J
