FS: Various amp PCBs, profits to DIYAudio

BrianDonegan · 29th June 2008, 07:47 PM

I am cleaning out the office/workspace, ad have a few sets of pcbs I have accumulated over the years that I will probably never get to building. Some I etched, some I bought, some I traded for, some were gifts. I am selling all of them for the benefit of DIYAudio.

For each set, the first person to email me a copy of a PayPal invoice paid to DIYAudio for the amount of the boards gets them (brian at twistedpearaudio.com).

If you plan on donating for a set, please post here first, as I won't be able to constantly monitor the thread. If you see someone has pledged to donate for a set, assume they are sold.

First up, a pair of F4 boards I etched from Veteran's design (http://www.diyaudio.com/forums/showt...446#post886446). I photo etched them and they came out great, just never got around to building them. They need to be drilled, but come with a pair (unmatched) of power Lovoltech JFETs (no in the picture). $20 with JFets for DIYAudio.

Next, a set of AlephX boards that I think I traded for (can't remember). I believe these are Kari's design, and come with eight output boards. SOLD

Next, a pair of Jens R's 6-device Leach Clone boards. These are on super heavy FR4 with 2oz copper. (If you don't want to build them, you can always use them to shingle the roof or repair the hull of a ship

) Beautiful boards (saving a set for myself). Forgot what I paid for them. $30 for DIYAudio.

Finally, 5 channels of GainClone SUSY boards (GC SuperSymmetry). These are based on a design by Terry Aben (metalman), layout by Russ White, boards funded by Ed LaFontaine (this sale to benefit approved by Ed some time ago). The boards have a small error requiring a trace to be cut and a small jumper to be added. I can perform this on each of the channels. Because there are an odd number, they will be sold as individual boards, so you will need two for stereo. Schematic and layout here: http://www.diyaudio.com/forums/showt...419#post856419
$10 per board

Sale pending for the GC SuSy boards.

Russ has informed me that he has a bunch of the GCSuSy boards he is sending up to me. When I get a count I will put them up here as well.

Thijs

You are correct, that's how long it's been since I etched them. Sorry for the confusion there.

Brian,

If you do find more SusyGC boards, I would be interested
in a pair.

Thanks,
Dennis
