This was a one-off made by Exemplar 20 years or so ago that he later added his updated tube output stage (2016ish). I pulled it out to sell (I'm moving and can't keep much) and found it not working. I don't think it will take much to get it going again but it should definitely go to someone who can. The dac is shunt regulated pair of 1543s. I added tantalum i/v resistors later. The tube output stage is shunt regulated 6H6pi and sounds fantastic. I'll include the tube dampers. There's a bunch of finemet beads around the power supply and elsewhere, a bit of Stillpoints ERS paper I added later. Really, this dac sounded better than it should have given the dac chips. It has a nice wood front and I thought someone might want to clean it up, reuse the output stage and chassis and find a different dac. I will remove Exemplar logo before shipping. $320 shipped in the USA
