mystery headphone amp

post #1 of 6
Thread Starter 
So I'm getting a mystery headphone amp without a power cable. So far all I have are pictures of the outside and I was told it was built by a forum member, not sure which forum. Here are the first pics I should be able to get pictures of the inside tonight.

Hmm I do remember seeing this one some where. I'm 90% sure someone on Head-Fi made this.

I see a total of 6 op-amps. 2 of them are hooked up to a dual to single converter.  The op-amps hooked dual to single are opa637ap's then there is a single opa627ap next to the caps.  the other 3 are all buf634p's.  Any idea on the power cable i'd need for this guy?
