For sale is a vintage Supex SDT/180 Step Up Transformer. Functions perfectly, all settings and switches work well. As you can see from the pictures cosmetically it has some bumps and bruises.This was the topline SUT that Supex introduced with its 900 series cartridges. From the Vinyl Engine: "The Supex SDT-180 provides the ultimate in audio performance and user flexibility . . . In addition to input and output impedance selection, the SDT-180 has input provision for two cartridges and a switch position to by-pass the transformer." I have 127 perfect transactions on Audiogon. Thanks for your interest. Specs --
