The Fisher 500-b
This item is for Local Pick Up Only
This receiver has been brought back to spec by our technicians and has been completely cleaned out and fully calibrated. New LED bulbs were installed for the front panel and a new old-stock volume knob was installed. It has been equipped with new JJ Tubes for the output and new Electro-Harmonics 12AT7s for the tuner section. There are still some Telefunkin tubes that test good. Lastly, some new resistors have been installed.
Cosmetically, it is in great condition for its age. The faceplate is in excellent condition, but there are some markings on the chasey and some minor pitting. All normal things for an amp of this vintage.
