“PAiA 9700 Series Modular Synthesizer in Excellent Used Condition

This auction is for a full 19” FracRak of PAiA 9700 Series modules, including one each of:

FracRak with Power Supply Wing, 9720 Dual VCO, 9730 Dual VCF, 9710 VCA Mixer, 9734 Dual CV Source w/ Mix and Attenuator, and Blacet 2210 Multiple & Attenuator.

Note: These are NOT Eurorack form-factor modules. FracRak is PAiA’s version of rackable modules. It uses a standard 19” rack mount frame size, but the modules are a different, slightly taller height. The only other synth company that used this type rack was Blacet, as far as I know.

These were built from kits in the 90’s. Not those little snap together kits like Korg and Moog are selling now. These are “total” kits down to the individual component level. Every resistor, capacitor, IC, pot, switch, wire etc had to be hand soldered in place. It took many hours to assemble a full set of modules like this.

I have tested this system and can only find one issue; the VC1 input on the first VCO doesn’t seem to work. You can still use the VC2 input just fine. Probably an easy fix but I just don’t have the time or knowledge. Scott Lee at PAiA technical services can probably talk you through the problem if you want, or fix it for you if you send it in. PAiA still sells and supports these modules. ” Click here to visit listing on eBay

“This paia keyboard came to us in a package deal. It was part of the 4700 modular system (see our other listings for a full system). It’s being sold strictly as is for parts or repair. We didn’t test it but we’re sure it’s not working because some wires have been cut. While we repair most vintage analog synthesizers, we don’t work on Paias here because they are relatively low value instruments so, strictly from a business perspective, it’s not feasible for us to pay our tech to fix it. However, Paia schematics are generally available on Paia’s excellent website forum and Paia gear is typically relatively easy to repair. Since most people shopping for Paia are DIY electronics hobbyists, most Paia buyers would probably enjoy such a restoration project. If you’re not capable of fixing it yourself, perhaps Paia knows someone who restores these. ” Click here to visit listing on eBay
