Vintage Tube Amp

Power output: 25 watts per channel into 8? (stereo). Frequency response: 25Hz to 25kHz. Total harmonic distortion: 0.8%. Input sensitivity: 4.4mV (MM), 440mV (DIN), 280mV (line). Signal to noise ratio: 80dB (line). Channel separation: 50dB (line).

Still needs a bit of work. All transformers work as they should.

Have this very nice Fisher 500 Mono Receiver recently serviced. Works very well pulls in stations as a fisher does. So if you can pick it up and save some cash. Take a Visit, to My Store.

Vintage FISHER X-202C INTEGRATED TUBE AMP AMPLIFIER (PART or REPAIR). NOT WORKING (PART or REPAIR).

Console pulled The Fisher 460A vintage EL84 tube amplifier approx late 1950′s or early 1960s (See label and serial number in photos). This amp has been fully restored electronically w/ modern capacitors + modifications to account for fact that stereo tuner is no longer present in the console, thus a bias resistor modification is made to properly bias the tubes (See 20 watt gold power resistor mounted to underside chassis). All capacitors and components are top quality such as Nichicon electrolytic and classic “Orange Drop” coupling caps, etc. The original top-side “MULTI-CAN” large capacitors were left in-place for vintage aesthetics while all new capacitors for the DC tube supply voltages were built into the underside as shown in the photos. New rectifier diodes were also installed as shown. A thermistor was added to the A/C input side to soften start-up current surge to the tubes and also add slight voltage drop to account for higher line voltages in today’s homes. The tubes are (2) Sovtek EL84 + (2) Russian 6P14P (EL84) for the power output + (2) 7247 for input stage : The amp, since it hadn’t been run in a while was “burned in” on the bench for approx 2 hours and ran perfect. I re-checked the bias and supply voltages and everything was in-spec. No hum, no sound issues – it’s running great. I will include a marked-up schematic and an original un-marked schematic to show the modification(s) and resistor values performed and needed to make these Fisher console amps run properly in stand-alone mode as was done to this one. An ON/OFF power switch was added (it appears the green LED light in it is out, but does not affect the power switch function). There is also a custom mesh steel plate bottom w/ plastic feet that was added allowing proper ventilation to keep the tubes running cooler. The bottom plate is steel – I left it un-painted as a new owner may want to paint it a custom color or build a wood case for the amp etc and thus it shows a bit of light surface rust as it’s not coated at this point. This amplifier is intended for a vintage tube amp collector or similar who is fully aware of what they are looking at in the photos and how to safely handle a tube amplifier if they remove the bottom cover etc as dangerous voltages are present.

Fisher Model 500-B FM Stereo Receiver. The receiver works and sounds very good. It passes a signal in all inputs. As you can see in the images, it is an exceptionally clean, low hours unit. The preamp tubes are all Telefunken 12AX7 tubes as can be seen in the images. There is one end bright missing from the tuning knob. The capacitors look to be all original. You will likely want to replace them all for the sake of reliability, longevity and even better sound. Includes cabinet and Manuals as shown. Overall, a nice unit that will make someone a great daily user with a little maintenance and restoration.

Original the fisher wood pre amplifier or amplifier cabinet. Across from inside lip 14 15/16 across. Front opening inside lip to lip 4 1/2. Top to back of cabinet 11 15/16 Pictures.

Listed as for parts or repairs. Powers on but overheats seriously. Smells like burnt when powered on. Comes with tubes and knobs. Please see detailed pictures.

Fisher 500 C, listened to this unit for years. Still working, just don’t listen to anymore. Unit is in nice shape for its age, review the pictures. Black metal grill is easily seen in one picture. Grill is off on the picture showing the tubes in the back of the unit. I will include the cooling fan if you are interested. Fan is mounted on a wood stand with foam pad, I used for airflow when listening.
