B1K Preamp

First off, this is not either of the two units that I was working on as described in the B1K thread. I actually had nothing but success with this one. I really like building these and going with different, sometimes the same look as the one before it. No headphone output here FIY.

Anyway, I built this with yet another 554 cigar box. It does look sweet, Made an oversized power supply for it with good filtering designed by Pete Millett. Mostly, the things that I added are cosmetic, but also it is a heavier unit with the thought vibration control behind it. Note the Pete Millett isolation mount for it. Also, I will point out that there are 2 inputs, each with a different level so as to have more control of source input. One input is about 12db down from the other. Questions welcomed.
$400+ shipping.
