My great Uncle was in the recording industry and often received gifts from other artist. He loved gifting my Father with stereos and record players. My Father recently had this Fisher 500 C serviced by one of the best HI-FI service/repairmen in NJ EBC Electronics. Pictures show all functions, tubes and burn in no smoke just tubing. The Fisher 500-C features a full function pre-amplifier section with twin phono inputs, auxiliary input, monitor input and tape input (for direct connection to the tape head).
