“Here we have a one of a kind custom PAiA built into an old suitcase built By Steve Alcorn the vice president of engineering at Linn, the synth is an expanded 2700, Steve pre-wired it up like an Arp Odyssey, so it is semi-modular rather than fully modular, so you can play as is or changer the internal connections. It has not been powered on in 40 years so will need a rebuild or replacement of power supply and a recap, in cludes original 1/4″ patch cables, suitcase has a key and there is another key to power the synth on. Comes with every pamphlet for each module used. Steve also signed the outside of the suitcase.” Click here to visit listing on eBay

” This vintage unit has four rare assembled PAiA modules in a wooden case. This series was released in the mid 1970’s and sold as kits that you could build yourself. I have tested the power supply module and it works. However the other three modules are not connected to the power supply so they are untested. The manuals and schematics are available online in the PAiA website archives.

The modules included are as follows.

Power supply – Model 2720-7. Tested and working
VCA – Model 2720-1. Untested
Envelope follower/trigger – Model 2720-11. Untested
Function generator – Model 2720-4. Untested

In great shape for its age. Scratches on the face plates and wooden case. Modules not connected to power supply. Please see photos.” Click here to visit listing on eBay

“Untested assembled PAIA 4700 analog modular synthesizer with 2700 and 8700 series parts.

These kits were assembled in the 1970s and installed in a wall cabinet in a basement den. The
manuals were stored in a garage and at some point got wet, but were dried out and have been in
dry storage for 25 years.

The modules were removed from the wall cabinet 25 years ago and have been stored in boxes
in dry storage ever since.

These modules are unrestored, untested and have not been powered up in decades. The modules
will be bubble wrapped individually for shipping. Please email with any questions or clarification on
modules labelled as “xxxx” that cannot be determined from photos.

“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

“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
