PAiA Fatman

This unit is for someone who likes old school equipment and knows how to work on synths,etc.
I’m wanting something a bit more modern and automatic.” Click here to visit listing on eBay

PAiA 4700 Series Modular Synthesizer

” You’re bidding on an analog “patch cord” monophonic synthesizer that contains all of the fundamental modules needed for music synthesis. I assembled this synthesizer in 1980 using 4700-series kits from the legendary PAiA Electronics, Inc. in Oklahoma.

This synthesizer was in “working” condition before I stored it away. I was already an experienced electronic kit assembler at age 18 when I assembled all of the modules. I used terminal strips to create “bus bars” inside the module cabinets to conveniently provide the three supply voltages (plus ground) to all of the modules. Once I got to college at PSU I begged an Electrical Engineering professor let me use a frequency meter in a lab to calibrate each key of the keyboard to the proper pitch. I recently applied power to the cabinets and proved that the power supplies are working, but their output voltages will need to be recalibrated according to the manuals. I say that this unit is “working”, but I never really got it to make the sounds I was hoping for…” Click here to visit listing on eBay

PAiA 2700 / 4700 Modular Synthesizer

“For sale is a vintage PAiA Modular Synthesizer.

Comes as shown. Untested. Not all of the modules appear to be fully connected (loose wires to busboard) and some aren’t screwed into the frame. I have NOT even tried to power this one. Assume it will need some sort of going over/repair to get it up and running.

Some of the RCA connectors have oxidation. The bandpass filter has 1/8” jacks instead of RCA. There are a few and knobs missing. There are two reverb tanks mounted inside for the 2 reverb modules.

The outer case has a little wear and some peeling near one of the edges. From a smoke-free home. “ Click here to visit listing on eBay

PAiA Electronic Synthesizer Module Kits

“PAIA Electronic Synthesizer Module Kits 9730/K, 9710K, and 9710frm Unassembled. Condition is For parts or not working because I have no way of testing them before assembly. These are electronic kits from years and years ago. These came to me unopened, so I assume they are unchanged from the factory, so all the parts should be there. I have no way to be sure. The 9710K and 9730/K kits each include a pre-drilled printed circuit card. The 9710frm kit contains a pre-drilled, pre-printed control panel blank. There are NO instructions or diagrams, just the information sheets seen in the photos. If you are a PAiA synthesizer enthusiast, you will know what these are. I hope they will be useful to you!

PAiA 9700 Modular Synthesizer

“Paia 9700 series modular synth rig has been meticulously soldered with high-end audiophile solder. This unit includes a 8 step sequencer that incorporates the Ken Stone Sequential Switch ([link removed by eBay]) which is routed to a set of 8, completely bypass-able, control voltage knobs. This unit has two transformers, and two power supplies. One for the 9700 modules and one for the sequencer/potentiometer bank. This has been working in my smoke-free studio for 10 years. VCO 1v/octave tracking may need re-calibration, which is easy: I will include paper instructions and documents for each and every module including power supplies. Wooden case is sturdy white oak. Includes a handle on one side. Three power indicating LED’s are on a front panel that includes a few multiples (3.5mm and 1/4″ jacks wired in parallel), but the LED’s are not currently connected- this doesn’t effect function. This rack has plenty of LED’s!” Click here to visit listing on eBay

PAiA 4780 Sequencer

“If you are a PAiA Phan you know what this is and how rare it is! There are a few scratches on the face plate, as you can see. Also my beefy power supply kept blowing the 1/8W 47 Ohm resistor so I am including a few 1/4W for your DIY hands to replace. My eyesight and unsteady hands would only make matters worse! Last time (before it blew) it was working fine as were all the LEDs.

If you are not familiar with the PAiA 4700 series of modules this is not the sequencer you seek. It is not Eurorack (it’s not even FRAC and PAiA invented FRAC!). The power this puppy uses is +18, +/-9V and Ground. Those are not banana jacks for the CV and trigger outs. And because the pin jacks are not grounded, you would need to run a ground wire between the sequencer and whatever you are sequencing (Unless – of course – you are mounting the modules in a PAiA system cabinet using a common ground).

Having pointed out all the caveats, this is an incredible device. It is expandable with other 4780 sequencers. I has 3 running at one time. It’s a maximum of 12 stages. This turns it into an amazing envelope generator or LFO.

I will include some pin jack cables and I think I may even have pin to 3.5mm. I will also included the using and assembly guides.” Click here to visit listing on eBay

PAiA 4700 Modular

“Up for sale is this vintage PAiA 4700 Modular Analog Synthesizer W/ upgraded keyboard controller and extras. It’s condition is “Used” but system is in very good condition. The case and fittings are all in great shape. Both the synth and upgraded keyboard were assembled by a former PAiA engineer and this sale includes a bunch of extra hardware left over from his build. In addition to manuals for every installed module, some of the extras include various patch cables, IC chips, switches, potentiometers, a remote volume knob as well as an additional un-assembled Watt Block module (w/ power supply).

*This item has not been fully tested*
I do not guarantee that every module and/or feature works as intended. I’m not familiar with vintage modular set ups, so minimal testing has been done. However, I was able to create a patch that confirms the system powers up and can produce sound (see youtube video). Just from the appearance and condition alone, I really see no reason that it is not working properly although you are purchasing it as it sits.

Modules include:

– 3 Voltage Controlled Oscillators
– 2 Envelope Generators
– 1 Multi-band VCF
– 1 Watt Block
– 1 Power Supply
– 1 Inverter Buffer
– 1 Balanced Modulator
– 1 Envelope Follower
– 1 Control Oscillator
– 1 Mixer
