Heathkit AA-21D Stereo Germanium Solid-State Amplifier – Fully Restored, Excellent Working Condition. This Heathkit AA-21D stereo germanium solid-state amplifier is an increasingly rare piece of vintage audio history-especially in this condition. A great opportunity to add a properly restored classic to a serious vintage audio collection. The amplifier has been completely restored internally and is in 100% working order. All electrolytic capacitors replaced with modern, high-quality audio-grade units. All carbon composition resistors replaced with modern metal-film resistors. Output power transistors replaced with a matched set of New Old Stock (NOS) germanium devices. Original germanium transistors are now quite rare and often noisy; this matched set performs exceptionally well. Original power cord replaced with a modern 3-prong grounded cord for improved safety. Current limiter installed to reduce wear on the main power switch. Dial and indicator lamps replaced. All controls, switches, and potentiometers cleaned for quiet, noise-free operation. The unit has been thoroughly cleaned but does show honest signs of age. Cabinet is structurally solid. Scratches and visible cosmetic wear are present (please see photos for details). Printed copy of the schematic included. Tested for approximately 2 hours paired with AR-3a speakers. Please feel free to reach out with any questions or to request additional photos.

Heathkit Model A-8A Tube Amplifier with 2 NOS 6L6GC Matching Tubes. Only the A-8A Amplifier and 2 additional Tubes come in this sale.

There is just one tube included a 5R4 rectifier. Just acquired a massive lot of gear, will not be spending time per unit to acquire parts/tubes and/or have serviced. May work amazing, may need parts, service, repair, restoration, calibration etc. Will be packed well, but will be expensive.

Belonged to my uncle who had an antique/vintage radio repair business for over fifty years. He used it to test some of the things he would repair.

100% working, just had it tested and serviced. Very clean condition, aside from mismatched output tubes my tech says it has no issues, easy enough to switch out if you choose to.

This Heathkit A-9C was included in a large estate we recently acquired. Like most of the equipment in this collection, this piece was found in storage. It’s in pretty nice cosmetic condition and clean. However, my guess is that it hasn’t been used in years (possibly decades) and as a result will most likely require service. All capacitors look to be original. All tubes are vintage American (Sylvania and GE). We simply don’t have the time to test everything right now given our tech’s limited availability. The bottom line is this… You’ll receive your item on time and in perfect condition regardless of how big, heavy, or delicate your item may be!
