Vintage Tube Amp

VINTAGE EICO MODEL HF-20 TUBE AMPLIFIER.

Vintage 1962 HH Scott Stereomaster 222C Tube Amplifier – SHOWN WORKING READ. They will be pulled using gloves, and will be labeled as to exactly where they were pulled from so they can be placed back in their original locations. About this unit: When the unit first made it into my hands it was missing all knobs and I was unable to get the unit to power on (which turned out to be just because I didn’t know how). I sent the unit off to my technician a retired E. E and had him give the unit a once over. While he was able to get the unit to power on he wasn’t able to get sound out of it. So he ran some tests and got the unit up and running again (his full notes can be read at the bottom of the listing), in total he. Cleaned the selector switch’s using deoxit, allowing the unit to properly play sound again. Tested all electrolytic capacitors with an ESR meter and found that they were all in good working condition. Tested and confirmed all tubes in the unit were working as intended. Ran the unit under a dummy load at 20WPC for 2 hours to ensure the unit wouldn’t blow itself up. In his testing he found signs the unit had previously been worked on, finding many (but not all) of the ceramic tube capacitors had been replaced with “Orange Drop” caps (see final photo of the unit on the listing). The note from my technician, and a printed copy of the owners manual will be provided with the unit. NO original packaging, manuals, or other accessories included. Feel free to message with any questions related to this listing. DM us for more information. Scott model 222C Stereo Laboratory Amplifier s/n 151945 component date codes 1962. All of the knobs are missing. Complaint was that it would not power up at all. I found that the tubes did light up, but that indeed, there was no sound. By trying all of the controls, I found that the tape monitor slide switch was intermittent. Treating that switch with DeOxit fixed it. Other tests and observations: I also applied DeOxit to the selector switches. No treatment of any of the pots, which were quiet and felt smooth. Testing the electrolytic capacitors with an ESR meter found that they are all okay, with ESR numbers far lower than the series resistors. Tested the tubes, which were all okay. The 7178 output tubes have no brand visible, but all 4 appear the same. Three of the 12AX7 input tubes are Telefunken, but the fourth is Sylvania. Removed dust with compressed air and mild cleaning of the chassis with a damp cloth. The amplifier was tested powering speakers and a dummy load at up to 20 W/channel, and about 5W/channel for 2 hours. As received, this amplifier was missing all of its knobs. They were replaced with new black bakelite knobs (Davies Molding p/n 1104). The new knobs do not match the originals, but they are clean and functional. They are easily changed if original style ones can be found. Note that there are some signs that this unit has been worked on before, mainly that most, but not all, of the white ceramic tube capacitors have been replaced with Sprague “Orange Drop” caps. Also the bottom cover is fastened by just 4 screws, 5 others are missing.

This is a very old amp.. Can see in the pics the tubes glowing.. Not sure what its for.. Weights about 22 pounds.. Measures 17 inches long.. Cord has been added on to (pics).. Screws holding the top cover to the bottom.. Couple screws are not original.. But holds it on.. There is no cover on the bottom.. Please check all pics..

Please note there are minor scratches and marks due to age. Please note that it is a used item. Kindly refer to the product description for more details. If you have any questions, please feel free to ask.

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

VINTAGE EICO MODEL HF-20 TUBE AMPLIFIER.

This is a used Lux vacuum tube amplifier that has been tested. It requires four 6RA8 vacuum tubes to operate (not included). Deteriorated components such as capacitors have been replaced. The main unit has scratches and rust, but there are no severe stains or dents.

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.

Awesome stand alone amplifier. This is one great sounding amplifier, it has been rebuilt from the ground up. All tubes tested strong. The specs show approximately 20 watts rms per channel. It has an extremely high level of sensitivity so it get loud quickly. Most amps have to have the volume up much higher to achieve the same level. Just a heads up so you start with the volume on your preamp lower. All components used of high quality. Thank you for looking.
