10 Vintage PAiA EKx series kits

via this auction

"And indeed you must be a fan or an old timer if you remember these kits, the PAiA EKx Experimenter Series kits.

The concept was, if you were a bit more advanced DIY-er than the usual kit assembler, these kits allowed you to customize your own build of a complete module utilizing the provided Curtis CEM chips, circuit board and a handful of support parts. Kits were available for VCOs, VCFs, a Dual Channel VCA and a VC ADSR. They come with a data sheet for the chip and an assembly manual for the card.

This auction includes one such finished module, a VC ADSR made using a PAiA 9700 series Frac panel as the faceplate. It worked the last time I tried it, which has been several years ago. Should still work but I can't say for sure, so I won't. Has a standard PAiA power connector attached. VERY basic functions (no repeat function) but lots of mini jack VC ins and voltage outs, including an attenuated output and a fixed output.

Here is the deal on the unbuilt kits - the foam pieces that used to hold trim pots, sockets, etc. have turned into dust. TOTALLY. So all the bags with the parts, minus the Curtis chips which are packaged separately, are full of the black foam dust. It's a mess. You could clean up the support parts or throw them away. What you are really buying these for are the circuit boards and Curtis chips. The rest are common parts, and the included parts (things like trimpots) are pretty cheap ones.

Some of the bags have been opened and are probably missing some of those support parts anyway, but all but one kit has the Curtis chip and circuit board present. I do not claim all those support parts are there. They have been shuffled around for years and most likely some of the kits are missing some resistors, caps, etc.

The following kits are included in the auction:

1 EXx-10 VC ADSR
1 EKx -20 VCF
6 EKx-30 Dual VCA (can be set up to be Exponential or Linear response)
2 EKx -40 VCO (ONE OF THEM IS MISSING THE CURTIS CHIP)
a small bag of parts
and the assembled EKx-10 VC ADSR module

I make NO PROMISE that the Curtis chips are good. They should be, as they are still in the original packs, but who knows..."
