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
