Bob's Devices SUT with Sowter 1951 transformers. With Cardas connections. Inputs opposite of inputs, with ground "lift" switch. It is a 1:20 step up audio transformer (26dB) switchable to 1:10 (20dB) built with OCC wire. Essentially new with only a few hours of breakin. I've decided to go with a wavac phono stage which gives me all the flexibility I need for my MC cartridge. Complete details on Bob's Devices web site. You can return the unit if not satisfied (subject to same condition as received, agreed to trial period, you pay shipping/insurance/reimburse Audiogon selling fee).
