Hi Folks, Added some new stuff, deleted sold items.  Items located in Brooklyn, NY USA.  PM me if interested.

Pair of Helios clone preamp cards (Mus1k_freak's Heli-Yos: https://groupdiy.com/index.php?topic=55283.0)
One has my HPF mod and variable gain pot, the other does not.  Both are stuffed and working from my DC power supply (AC supply parts NOT fitted).  Schematics included. $25 plus shipping.

The JH Cards detailed below are still available as well.

Here is a pair of somewhat unique amp cards.  I bought them in a lot from another GDIY member, then recapped them and drew out the schematic by hand.  Specs are pretty impressive, not dissimilar to SpectraSonics cards.  Read the thread here: https://groupdiy.com/index.php?topic=63589.0  Comes with a copy of the schematic, with added DC voltage measurements.  $50
