Vintage Tube Amp

This particular set tests as average / used and are fairly closely matched, with all 4 date codes the same. These should still have a nice amount of life left in them. The tubes’ test results are displayed in the photos New 6L6 Spec 100% = 6,0. See the photos for physical / cosmetic condition. Also, t he tube boxes are original reused RCA boxes, and not original to 6L6s or these tubes. Additional Note: The getter flash on one tube is quite a bit more faint than the others (the one testing 82% Gm), this is purely cosmetic since as mentioned above this tube still tests satisfactory and sounds nice. Notes Regarding Tube Tests. All tubes are tested on an Amplitrex AT-1000 tester in the automatic Fixed Bias Mode (for the most conservative results). Test Results are for a general reference only, and are not a guarantee of performance, nor a guarantee of how they will test on your tester. No real world (audio) performance measurements are taken.

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.
