BTW I own two of his DACs. They are incredible. Smoke the Sabre designs I have heard.

Built the supply tonight. Very nice results on the bench so far. Will hook it up to a headphone amp this weekend. Output voltage is accurate to about 3-4mV. Moves around in that area as long as ambient temp is steady. My sink is running about 46C right now. Will use a bigger one next time. If I blow on the sink the output voltage jumps around a lot til the temp of the sink stabilizes. Scoped the output and it looks fantastic.

Well, I built it to replace a battery supply on the headphone amp and it serves the purpose well. After some tweaking there is no distinguishable difference. Thats a good thing

Thing is very touchy with temp. The sun moved across the room and when the sunlight hit it the offset from +to- was a few volts. Will have to put a load on the transformer and heavier load on output to test further.
