Think "Millett Max" for the financially impaired... or maybe "Millett Min"?
The idea was to design the simplest, lowest cost hybrid headphone amp possible. It still had to perform well and sound good, of course. I think I suceeded... it sounds very good.
If you're coming to CanJam, you can listen to it. I think Nate M will also have his version there.
As Pete said I've already built and been using one of these for a while (month or so) for my amp at work. To say that it's a bargain would be an understatement. The build, even for non-ptp folks like myself, is easy and straightforward if you can follow a schematic. Here are a few choice shots of mine, I'll upload a picture with the knob mounted some time soon.
Big thanks to Pete for another great project for both new and old DIY'ers!
I believe that there's a BOM on Pete's page that includes pricing information. In my build the parts order from Mouser was ~$40 shipped ($11 chassis included) and I think tubes and sockets set me back another $10 shipped. If you have anything in the way of parts laying around (like I do) you can build one of these for under $50 including everything without breaking a sweat.
They're $1.10 each. Pete is loading us down with those pricey NOS tubes again.
Nice design! Might have to put one of those on my shelf shortly.

Pete's given us another great one! This thing looks cool - I've already started ordering parts. I had a bit of trouble finding the power supply, but this link should help you guys:
The guy is down to 92 from 100 in the last hour, so they may be going fast!
I'm guessing the ingenious method of loading the MOSFETs with the tube heaters means they're already biased at 150ma. Sounds like a neat trick all the way around.
