This is kind of a half-baked PIMETA, as I built it up for use at the office while I was waiting for some other amp parts to come in. It's in a Serpac case w/ battery door, but I never used it with batteries. I soldered on a pigtail with a DC jack on the end, and used it with a 24V Elpac wall wart. I would strongly recommend insulating the leads on the DC jack if you plan to keep it the way it is.

Here are the specs:
OPA2227P for left/right opamp
OPA627BP for ground (this is complete overkill, but it is what it is)
surface mount BUF634, 1 per channel
buffer bandwidth resistor is 220R
Alps volume pot with integrated switch
High-quality 3.5mm mini stereo in/out jacks (these are the expensive ones from Digi-Key)
Cerafine 470uF electrolytic caps
No input caps
Class A biasing
big yellow power LED

[size=large]SOLD![/size]

$80 shipped via USPS Priority Mail w/ Delivery Confirmation. I only accept PayPal and only ship to the USA.

Edit -- never mind, I see the buffers are soldered onto the bottom of the board. Free bump for a very good deal.
