Vintage Tube Amp

Up for sale is a vintage Ampex Model 620 powered amplifier-speaker monitor. This unit is in beautiful cosmetic condition with a clean faceplate, original knobs, intact grill cloth, and a solid suitcase enclosure. Ampex Model 620 powered amplifier-speaker monitor I have used for years. Sometimes in my studio and sometimes in remote recordings. It has a JBL speakers and both units are in very good condition all original with power cables. I did recap it about 11 or 12 years ago. The brown leather-like exterior shows some minor scuffing and signs of use consistent with its age, including minor paint scrapes on the side ventilation grill, light surface oxidation on the metal rim around the rear recessed panel. When closed, the case measures approximately 17 x 14 x 8 1/2 inches and weighs about 24 pounds. This item is listed in multiple sites as well as locally. There is a slight chance that it may sell before I can remove the item from this site. I reserve the right to cancel the listing at any time.

Up for sale is one H. I powered it up with a Variac Transformer. This could be a great project for someone who wants to tinker. Manufactured in the late 1950s (around 1958). It includes a multiplex output jack anticipating future external stereo decoders before the FCC officially approved the FM stereo standard in 1961. Utilizes a direct-drive tuning setup through a planetary gearset (vernier tuning) rather than a traditional springy dial-string. Built using Scott’s wide “C” case/chassis format.

If you’re an uncompromising collector of antique technology, make sure to check out all my listings after you look at this one. I don’t think you’ll find a better, broader or more balanced assortment of technical antiques anywhere — hundreds of listings each year, almost all of them featuring eye-popping “gee whiz” gadgetry in exceptional original condition. Here are three working Western Electric 216-A amplifier tubes with good emissions. When tested on a Dan Nelson calibrated TV7/U tube tester, with 6.3 volts to their filaments, the tubes scored 44/35, 45/35 and 54/35. They were further tested in an early 20′s battery amplifier, and they all work well.

The stock circuit had four 6550 output tubes in parallel push pull. Stamped codes on base are FT5426433 and 138243E. Please ask questions if you have any. Item has finish imperfections and wear. Only what is pictured and described is included – if unclear, then ask to clarify.
