Vintage Tube Amp

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.

Scott Stereomaster 340 Receiver. Up for sale is a A rare used 1963 H. Scott Stereomaster 340 vacuum tube MPX receiver. All tubes were tested and they are good to N. The original four Amperex 7591 tubes test excellent at 8,500-9,250 umhos. Controls work but there is switching crackle in some. The unit is in excellent cosmetic shape with a few small marks that are shown in the images. The plastic tuning dial is missing. With the bottom cover off, everything inside looks original to the factory design. This unit does partially work but will need work to bring it back to factory spec. I have included a fairly hard-to-find owners manual and schematic for this unit. This is a highly sought after integrated tuner with great build quality. With some TLC this will make the centerpiece of a fantastic stereo system for someone looking to explore tube audio. The unit is very heavy and will be packed safely. I will pull some of the tubes and pack them in tube boxes.

This old HH Scott receiver had been stored in a garage for years, likely decades. It was pretty dusty but cleaned up reasonably well with some compressed air and brush. We removed the 7591 and 12AX7 tubes, but otherwise it’s exactly as we found it. Due to the fact that it’s sat so long, we’ve made no attempt to test it. It’ll likely need new capacitors or other components. If you prefer one carrier over the other, please make that request when paying for the item. Rest assured, you’ll receive your item in excellent condition! WHAT’S INCLUDED IN THE SALE: You will only receive what is shown in the photographs.
