Mods, if this is in the wrong place, please move it.
I have a couple of extra PCBs for making 2 different versions of the Szekeres amp. I would like to sell them off with the money going to my favorite charity: http://www.treehouseanimals.org/ The way this works is you PM a bid, and in about 48 hours I'll contact the highest bidders. At that time, you just PayPal the money straight to the charity and I'll send the boards.
There is one board for a 3 channel szekeres. Details about the project can be seen at http://www.geocities.com/rjm003.geo/...o/diy_sze.html (this is not my design b/t/w/), and a pic of the actual board is attached to this post: http://headwize.com/ubb/showpost.php...=54051&fpage=3 It comes with 3 unmatched 2sk213 mosfets -- you'll need to buy a few more from Bdent, but hopefully one of these 3 will help in getting a matched set.
There are also 2 pairs of boards for the traditional Szekeres amp built around th IRF510 (available from digikey). The boards are dual mono and contain their own power supplies. You need the components + a transformer and a couple of big heatsinks (please note that these boards are untested, so bid accordingly).
I should also note that I am not expecting these to sell for higher prices than they might otherwise cost. Bids in the $20 range are expected and appropriate, but higher is also great.
The schematic and layout is as follows:
