I'm considering having some of the original Leach amp PCBs fabbed, anyone else interested in some? Not the SuperAmps, just the plain jane originals, version 4.5 of the pcb. It's looking to cost around $220 - $250 plus shipping, be it 5, 10 or 25 boards, so it doesn't make sense not to make 15 more for only $30 more. So say 25 boards, they'd be ~ $10 each plus shipping.
So why am I going with the original pcb and not the Jens board or something like it? I have all the parts for the project from when I abandoned years back, but the PCBs were done using a proto process and maybe not all the etchant was neutralized, that and the traces aren't really very thick, as a result they've pitted. In addition I have some slick heat sinks with heat pipes that are almost the same size as the pcb, I should be able to cram 5 amp modules into a 4u or 5u chassis with room for the 1kVA toroidal transformer as well.
