“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

One (1) 4711 4/2 Mixer
Two (2) 4761 Wing (One has been modified)
One (1) 4770 Watt Block (This unit requires 2 to be fully functional. Possibly there was an external power supply at one time due to one of the “Wing” units fitted with a jack but I do not have it.)

One (1) 2720-1 VCA (Voltage Controlled Amplifier)

I have NO patch cords or other accessories.

(see my other listing where I have a matching keyboard)

Vinyl is slightly coming loose on a few edges, a few light scuffs, missing a few rubber feet, a few light scratches on some modules but all in all it is in very good condition.

“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

“Really neat vintage synth, in great working condition. I restored it electronically 3 years ago, and have only used it in my home studio. I’m the second owner, and acquired it directly from the original owner whom purchased it in the 1970’s, I believe it’s from 1976. I have a bunch of paperwork for the synth somewhere, if I can find it(I’ll try, it’s buried in boxes somewhere!) I’ll include it as well. It’s worth noting that during the restoration, I preferred to keep the synth as original as possible, but electronically stable, and to make a 50 year old synth as reliable as possible. It includes and uses the original “pin” cables, so neat & rare. That being said, it’s still a very old synth, from the early days of modular synths, when slight changes in mains voltage and temperature variations manifested themselves in “interesting” ways. I’d assume that the purchaser of this synth understands that and doesn’t expect the oscillator tracking and tuning stability to be similar to modern synths. Please watch the Youtube video I created for this synth, which goes into great detail about the synths condition, and should answer any questions you have, and give you a clear idea of what to expect if purchasing.

Thanks!

”
We normally deal in meticulously serviced high value items. This item is of relatively low value and has not been given our typical treatment, as this would be cost-prohibitive. It is however described to the best of our ability below:

Our tech tested this and says the watt blocks are putting out the right voltage. Some of the wooden pieces in the back that the back lid screws into may need to be fixed or replaced if you want to put screws in all 4 positions. When this unit is powered up, the right LED lights up. The left one doesn’t. We normally refurbish our gear, but this is a low value item not worth paying our tech to work on, so we’re selling it as is. ” Click here to visit listing on eBay

“One of several modules from a box containing PAIA Modules, as pictured. Untested and includes everything pictured, most of the modules have a small bag with them containing the “pin jacks” that were removed. The faceplates are as pictured and many have a rather ugly look to them, never tried cleaning them up. No returns as these listings are as seen for parts or repair NO INTERNATIONAL SHIPPING – thank you!”

Physical condition good, as shown in pics. Keys move freely.

Therefore, it is listed as not working. I do know that it was assembled professionally and worked when built. Will probably need some restoration. ” Click here to visit listing on eBay

“PAIA Synth Modules from the ’70’s. VCA,VCO,Envelope Generator. Sold AS-IS. Condition is “Used”.

These worked perfectly…40 years ago!!! So have to sell them as-is because I couldn’t test them.
Everything looks good but ya know, after so many years you might be replacing some capacitors. Who knows.
I had a whole PAIA rig that these came from, all in a custom wooden enclosure and used the synth playing out.” Click here to visit listing on eBay
