These amps were built by the tech for Deja Vu Audio in Northern Virginia, wee their website below. Vu sells a lot of vintage Western Electric and builds quality amps with his logo. They come complete with a set of WE 300 B tubes with less than 100 hours on them, and are outfitted with vintage Chicago output transformers.
The two sets of binding posts are for 4 and 8 ohm outputs, and output is about 18-20 w/p/c. They will drive any reasonable speaker load as loud as you want. These amps are also listed on US Audio Mart, several Facebook groups, What's Best Forum and locally so may disappear at any time. Deja Vu Audio is the premier high-end audio dealer in the Washington, DC Metro Area.
Located in McLean, VA for 25 years, Deja Vu is renowned for its'sound above all else' ethos, eschewing flavor.
