Vintage Tube Amp

For sale is this rare vintage Webster Electric Type 81B15 Amplifier from circa 1951. This was checked for basic signs of life using a Variac to help preserve the tubes & capacitors after sitting safely in climate controlled storage for many years. The unit powers on great and the tubes glow healthy although no further testing has been done. An interesting note on this amp, it is covered in porcelain and has chrome plated handles. I happen to have some extra matching tubes for the unit lying around that I will include as well. The cord does have some beginning signs of dry rot but is still functional. If you have any questions please reach out and I will do my best to answer in a timely manner.

Vintage UTC Linear Standard MLF tube amplifier, manufactured circa 1954 by United Transformer Corporation (UTC). This is an extremely rare mid-century hi-fi amplifier built during UTC’s golden era and designed around original UTC transformers throughout. Units like this rarely come up for sale in complete form and are highly sought after by collectors, restorers, and transformer enthusiasts. I do not have the proper equipment to safely power or test vintage tube electronics, and no attempt has been made to plug this unit in. Due to its age, please assume it will require service, restoration, or parts replacement before use. No guarantees are made regarding functionality. Cosmetically, the unit shows normal age-appropriate wear and patina consistent with a 1950s amplifier. There is no obvious major damage visible. Please refer to the photos carefully, as they are considered part of the description and show the exact condition of the item. This model is documented on Radiomuseum and recognized as a high-quality Linear Standard / Williamson-style hi-fi amplifier built to showcase UTC transformer technology. Additional reference information can be found here. Serious buyers who are familiar with UTC gear will appreciate what this is.
