Vintage Tube Amp

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.

Up for sale here is this pair of used vintage 1949 250k ohm linear taper potentiometers. I don’t know who made these–each is marked “4-62, ” but that’s a part number, not a date or EIA code. These have short 1/4 round shafts. They test around 271.9k ohms and 254.7k ohms, so fairly close. These are very r are potentiometers and will work great for you, though they may need some Deoxit. These are for amps–they are probably too big for a guitar. Please see my pictures for details. If you have any questions, please ask. I have more potentiometers and other vintage electronics listed–feel free to take a look!

Here is a SUPER rare amp to find in the US – the UK made Linear Conchord! This one is in need of a rescue. This is a 30w amp designed to run a GZ34 rectifier tube, a duet of EL34 output tubes. These were the poor guitarists amplifier and were originally metal caged mono block looking amps available on the cheap to British budding guitarists. This one has an INCREDIBLE looking custom made cabinet to house the amp. This one has a US plug installed and no tubes and in need of a re-cap at the least. Currently the chassis is not mounted in the custom cabinet so I will have to pack carefully to keep it from rattling about. Very cool piece of British amp history with a great looking custom made cabinet. Available at Sunflower and Friends in Lockhart TX.
