Gents,

I have been kicking a ton of ideas around for a nice linear power supply for the SB3. My immediate thoughts are shunt regulation. So there are a couple ideas:

1) Cajole, pull, beg, cry in front of Dave Davenport to come up with a minimal reactance power supply for the SB3 (~5V at 2A). I only see him going for it if there is enough interest, and I think there is really only one person that's interested, and that's me!
2) Use Peter Daniels Universal Power supply board which uses Jensen 4 poles in a pi filter format, then plug that into a Paul Hynes shunt regulated power supply which will spit out 5V at 2A easily. Definitely more expensive than option 1 however.

But...Both options should compete with an all battery PS (like the $$$$ Optima Reds) and be cheaper and more user friendly.

I'm also reconsidering the PaceCar given the ASRC implementation of the RAKK dac II. I figure it will only be icing on the cake, given the icing is $1500!

Best,
Anand.
