Got my boards too, thanks.

I've put one of them together. It worked first time, which was nice. First impressions are good.

Excellent! I wasn't expecting another amp to be alive this fast, especially without a barrage of "why doesn't it work?" e-mail.

Depending on your headphones, you may want to manipulate R22/R23 to adjust the output gain of the amp. I'm using 1820 ohms for my Grado 125's.

gmarsh,

I'm populating my boards now and I have a couple of quick questions....
1. The crystal does not have solder tabs that protrude...does it solder direct, and if so, how do you be sure it flows under the tabs? I use solder paste for all my smd work, and it works well, but I've never done a crystal before.

2. I am curious about the numerous small vias you placed adjacent to some of the component solder pads.....are those just test points?

Thanks, Robert

Well, I think I got the XO soldered well...had to go pretty high on the temperature to get it to flow well.
