Power Supply Kit for Apogee Mini DAC

post #1 of 8
Thread Starter 
Does any one know where I can get a power supply or a DIY power supply kit for an Apogee Mini DAC?

Thanks

Looks like it needs a DC supply between 6-14V at a minimum of 1.25A

Why not build a TREAD using LM338, just make sure to use a big heatsink. Entire project cost will probably be < $40.

Thanks FallenAngel,

Where can I get the parts for it? Info?

I was thinking of a step like the sigma 22 (will it work)?

I'm new to the DIY side...any recommendations is greatly appreciated.

Grawk, Any noticeable improvement with the sigma 11?

BTW, what the heck is a sigma 11?

You won't need the Simga22, you'll need a single rail PSU like the Sigma11 (as grawk suggested) or Tangent's STEPS, it just depends on how much you want to pay. I'm sure the Sigma11 or STEPS (with LM338, not LM317) will be very good for it, but you're looking at about $80 for either of those or about $40 for the TREAD, which I'm still sure will sound fantastic.

Tangent (Tangentsoft) sells kits for his TREAD as well as TREAD and STEPS boards. Amb (AMB Laboratories DIY Audio Site) sells Sigma11 boards. I don't think anybody has kits for the Sigma11 (unless Jeff at www.GlassJarAudio.com sells them, but I think he only carries the Sigma22 kits).

Either way, all parts for either PSU can be bought from DigiKey or Mouser with personal preference going to DigiKey because they have Panasonic FM capacitors which are basically the best bang/buck PSU caps (and pretty much best in general).

From personal experience with both the STEPS and sigma11 it's going to cost a fair bit more than $80 to get one up and running. The STEPS is slightly less expensive but I'd expect both to run north of $100 at a minimum.
