Vintage Tube Amp

Vintage RCA MI-9289-B professional tube power amplifier, offered in as-found and untested condition. The chassis is factory marked MI-9289-B and retains its RCA identification plaque marked Radio Corporation of America, Meadowlands, PA, serial number M2004. The amplifier appears largely original and unrestored internally, retaining its large transformers, meter assembly, controls, wiring, tube sockets, and extensive original-era components as pictured. The amplifier retains tubes in the chassis positions marked RCA-6SN7GT, 12AY7, RCA-6L6GC, and both RCA-0D3 positions. All four factory-marked 6550 output tube positions are empty. The installed tubes have not been tested and are included as found. Cosmetically, the amplifier shows considerable wear from age, use, and long-term storage, including dust, grime, oxidation, discoloration, scratches, and general surface wear throughout. The meter is present and the front controls move mechanically. No attempt has been made to clean or cosmetically restore the unit. Due to its age and apparently unrestored condition, I have not attempted to apply power to the amplifier. It is completely untested and should be inspected and serviced by a qualified technician prior to use. No representation is made regarding the electrical condition of the transformers, tubes, capacitors, meter, or other components. This is an exceptionally substantial piece of vintage RCA professional audio equipment and is being offered as pictured for restoration. Please review all photos closely for exact condition, configuration, components, and completeness. Items come from a smoke & pet free home. Reference the photos and description carefully to see the quality of the exact product you will receive. Please reach out with any questions!

The amplifier powers up, passes audio cleanly, and controls function. It sounds absolutely killer with a gritty vintage breakup at perfect studio volumes.

The original cream faux-crocodile tolex covering has significant peeling, tears, and missing material on the upper corners, exposing the underlying wooden cabinet. Component Wear: The amp retains its original brown, ungrounded 2-prong power cord and vintage Mallory multi-section filter capacitor block. Like all electronic equipment from this era, it is highly recommended to have a professional vintage amp technician inspect it, convert the power cord to a modern grounded 3-prong safety cable, and evaluate the 70+ year old chemical filter capacitors for prolonged, safe modern use.

Up for sale, a 1967 Silvertone model 1482 tube amp in excellent condition and in perfect working order, complete with the full original Silvertone-branded tube set. With a 100% original circuit and a modern three-prong power cable, this Silvertone is ready for another 60 years! Manufactured by Danelectro in the USA, this amp is often referred to as the “poor man’s Deluxe” for its rich gain, touch-sensitive responsiveness, and 15 watt 6V6 push/pull tube power section, features which are all very reminiscent of the Tweed-era Fender Deluxe from the late’50s. This amp really does tap into what made Fender’s Tweed amps great, and at about 1/10th the price, the Silvertone 1482 is one of the best bargains on the vintage amp market. With simple controls for Volume and Tone for both the Mic and Instrument inputs, the amp also boasts a powerful bias-based tremolo circuit that has a great pulse and smooth waveform. The preamp is untouched, and the point-to-point, hand-wired circuit boasts the original capacitors, carbon comp resistors, and CTS pots which date to the late weeks of’66. Both of the original transformers are intact, and the amp is stocked with its original pair of Silvertone-branded 6V6 power tubes. A modern three-prong power cable has been installed, and the speaker is the original Fisher 12 alnico magnet driver, featuring a date code on the magnet bell from 1967. The original gray thatched covering is in good shape, with just a couple minor marks and one circular mark on the top of the enclosure. The original wheat grillcloth with sparkle thread is present, and the aluminum faceplate retains all of the original knobs and black silkscreen text.

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.
