“Hello, I have this listed as for parts or repair as I feel it needs some repair and their are no returns. When I 1st acquired it it came with original packaging and original manual and brochures. The original box has become brittle and is not included. I have misplaced all the brochures and original manual and those are not included. Years ago when I played around with it with manual [not included] as I recall most of the moduals worked and I had many hours of fun with this. I have lost the manual and at a lost of how to hook this up. I recently found one of the wiring examples on Google images and hook it up as such and it works. After playing around with it for some time I found the sound became quieter then when 1st hooked up. I noticed one or more of the controls a bit scratchy sounding and needing some cleaning. I do not know if it just needs cleaning or repair. While taking photos I just noticed a control on the back that looks kinda like a volume however I do not know perhaps that is the control affecting the sound. I can not guarantee every modual is working as they should.
Powers up ok and should be checked out by a technician for full playablility. Some modules may need work or adjustments. Solders appear to be good.Powers up OK and appears to be working but connectors need to cleaned.
Sold as is and should be serviced/adjusted by a knowledgeable technician.
There is space for 2 or 3 more modules which are not included.
Keys all move freely but should be lubricated.” Link

“PAIA Gnome Early Synthesizer

This was available in kit form in the mid 1970’s

Itis completely assembled and for the most part works.

The only issue I can report is the VCF appears to have limited functionality.

The resistive element is intact and it does work.

Requires two 9 volt batteris to operate.

Unit is in very good condition.” Link

“this synthesizer needs some TLC. here is what it does, the piano output sounds good, the strings output is on all the time…like a key is stuck in the down position, the filter sweep works and sounds cool…biggest issue: some of the keys do not work…across the board there about 4 NOTES that do not work on any octave.

the unit looks good with no major flaws…it is missing the top cover that covers the keys for travel.” Link

“Here’s a vintage PAIA 4700 modular analog synthesizer. 3 octave keyboard, 2 sided hinged rack with assorted components. I purchased this from an Estate along with about $6000 worth of vintage musical gear in excellent condition. I did not get any patch cords with it. It has not been tested, I wouldn’t know how to establish if the components worked properly or not, I’m a guitarist, bassist and drummer. Just from the appearance and condition I really see no reason that it is not working properly so you are purchasing it as it sits. From a smoke free environment.”

Modular, PAIA @ 23 May 2017, Comments Off on PAiA 2700

“This is a great introduction to modular synthesizers.

The unit is 90% functional, but the EG is not working. It is likely repairable as it was working previously. I purchased most of the modules off ebay and assembled them in my own makeshift case. I modded the vco’s with alpha trim pots and routed them to the front panel. The power supply is original but I added an inline AC filter at it’s front end. The power plug comes out of the left hand panel and is a standard 3 prong AC. The modules are power supply, 2 vco’s, bandpass and low pass filters, 2 vca’s, LFO/noise module, and EG.

This synthesizer is linear VCO’s. Circa DIY kit from about 1970. I’ve used a qunexus to control it as well as a beatstep and a korg sq1. It tracks in Hz per volt over about 12 to 14 semitones. This is by design as the original design had a keyboard which was tunes by individual key and trimpot. I started putting this synth together as a project to learn about modular synths but have outgrown it and moved on to eurorack. I am an electronics technician by trade so the build is pretty sound.

If you bid on this please be aware of what you are bidding on as I will not accept returns based on “thinking it was exponential”” Link

4700 “Restored Paia 4700 system. I put two solid weeks of work into bringing this back to life.

DOES NOT INCLUDE ANY CABLES – but I will include a small coil of vintage wire and some pin connectors so you can build your own power connectors. You will need to supply your own 1/8 cables though.

In excellent physical condition. All modules work as they should (warts and all – note that some knobs have strange travel end points, by design).

All electrolytic capacitors on all modules have been replaced! In nearly all cases I used high quality Nichicon PW caps. I also increased cap values in some places to reduce noise.

A number of ICs were replaced to restore full functionality.

All VCOs were tuned and calibrated in May 2012 – scaled for use with my Novation bass station as the CV converter (if that even matters). It has been unused and in storage since then. They are sensitive, and may need recalibration after shipping, so I cannot guarantee that it will arrive in tune.

Issues:
1) top right LED on sequencer is out, but the step works. An easy fix that I never got around to doing.
2) The 18V supply in this is total crap by design. Consequently, there is still some hum, even after recapping on modules that use it. I was testing the unit in Sweden, and it is possible that the hum was enhanced because of my power set up there. It may be lower when on proper US voltage/frequency. Regardless, after discussing this with Marvin Jones (ex-Paia), I came to the conclusion that the best step would be to just add a new isolated 18V supply. I have not done this though. It’s up to the buyer to do if they so desire.” Link

“Ok. So here goes. I put 8 new batteries in this and tested it out. To me it appears the knobs/dials need cleaned and then it would work. After trying it for 5 minutes it FINALLY worked when i turned a dial. It worked for about 1 minute and then back to not working. It started working when i was turning the dials randomly. Looks like i touched one again and then it stopped. All lights work. The light changes as it should on the selector. Speaker worked when it did for the one few seconds. The far left key sticks but appears to be too close to the front edge of the housing and so it binds when pressed down. All keys worked when i tried except one, then it stopped working all together, so not sure what that was. So this is sold as is and needs fixed up to be 100% again. Battery compartment is clean. Has wear here and there. I try and show everything in the pics.” Link

Original power cord is very good. Needs cleaning inside and out. I pulled a couple modules just to check quality of soldering since it was a kit, looks like the guy was pretty good at soldering. Not tested. I didn’t know where to start, this is the first synthesizer I ever touched. You get everything pictured.”

pai4700 “I’ve tested every module in this unit and for the most part, they are all functional. The two 2720-1 VCA’s are a mystery to me as to how or if they they are working correctly or not. One of the two I can get to work but the volume is pretty low. The other I can’t seem to get to work. I might be patching them wrong but there might be an issue with them too. In any case, one functions at a low volume and the other may not be working.

I bought this synth from a close friend. Everything seems to be original besides the odds and ends I replaced. I cleaned the pots, replaced the module screws, replaced the rubber feet, and replaced some of the patch cable wires, keeping the original jacks.

I’m including a bunch of patch cables. Some are original and some are new. You may need a few more but there are enough included to get some solid patches. 1/8 mono audio cords (eurorack style) work for the audio and E0512C speaker wire pins work great for the voltage connections (see picture).

Because this modular is old, I’m selling it as-is. Be aware that shipping this item has the potential to damage the electronics. It is unlikely but possible. I will take care to pack the item to prevent damage and I’ll be shipping through UPS.

As a buyer of such an item, I’m assuming that you understand the nature of vintage audio equipment, appreciate the quirkiness and character of analog circuitry, have at least a basic understanding about how this synthesizer works, and that you are willing and able to solder a loose wire if one happens to shake loose during shipping. Luckily, manuals on operating and assembling these synths can be found online if you need to repair or upgrade/restore the synth.”

paia “Powers up and all modules work. VCO needs calibration/tuning – the scaling appears to be off. Procedure is relatively simple and is in the manual, which can be found for free via a google search or on the PAIA website. Other modules may need calibration but appear to function as intended. This is not a fancy sounding, immaculate sounding synth – it is VERY raw and lo-fi. But the modules work. Don’t expect an SH-101 here! Case and modules are in great shape, but have light scratches and some black pen fill in over lettering (on a couple modules only).

Keyboard is Pratt-Read. Most keys make mechanical noise, and it needs new bushings installed to correct this (available for purchase online). But this is quite common on Pratt-Read keyboards, and all keys trigger fine apart from the noise! As with all Pratt-Read keyboards, there is some pitch variation depending on how clean the bus bars are at a given contact location. This unit could use some cleaning to correct. this.”

Modular, PAIA @ 10 January 2017, Comments Off on PAiA Fatman

fatman ” I am selling a PAIA FatMan Analog MIDI Synth that I built from a kit from PAIA several years ago. PAIA still sells this product and you can go to their site and read more about it. I bought this quite a while ago, built it, got it working and it has been in storage for a while.

This auction includes the FatMan, the power supply, and the manual that describes how to build the kit, how to tune the synthesizer and how the circuit works.

I hooked it up and ran it through the tuning procedure and it is working fine as far as I can tell. You will probably need to tune it because while I did tune it, you initially tune to something that has a known note and I didn’t have that.

It’s actually quite a bit of fun. There are sound samples on the PAIA page too. It is called FatMan for it’s nice deep sounds.

I won’t try to describe the circuitry. It has two oscillators and all the typical sections of a typical monophonic synth with a few extras: VCOs, VCF, ADSR, VCA. It has MIDI in and thru. You can set the input channel on the circuit board (set to channel 1 on delivery).

The firmware on my version is 1.7 and on the web site it is 1.9 so it would be worthwhile updating I think (simple chip replacement). The circuitry looks the same between what I built and what is currently being sold.

Power is from a wall wart power supply (included). It is rack mounted and this version does not come with a case, but you could make one. They also sell a desk top case now that you could probably buy and move to if you don’t want to rack mount the FatMan.” Link

paia “Up for auction is a nice lot of vintage PAIA Modular Synthesizer parts w/ case(s). I acquired this gear from a local musician who put all this together back in the 70s. His careful treatment of the gear has allowed it to survive and surface unscathed some 40 years later. I do not pretend to know much about this synth; it powers up nicely, but even if I had more than the 1 patch and 1 power cable supplied in the package, I would be hesitant to start poking around on the unit for fear I might patch voltage to an audio line. Though this synth was known to be working well when de-commissioned, it may today need some TLC and some cajoling to bring it back up to spec after a 40-year hiatus. Cosmetically, everything looks pretty good; the metal module faceplates look fantastic, and while the cases are not pristine or perfect, they are in great shape considering their vintage. The following is a comprehensive list of the gear:

4720 Voltage Controlled Oscillator Module (qty 2)

paia “PAiA “Strings And Things” Vintage Analog String/Piano Synth

Up for auction here is for a vintage analog keyboard from the 1970’s. This is one of those ‘string synths’ like the ARP Solina that uses analog circuits to imitate the sound of a string section. Actually these machines had a sound all of their own – think “Love Will Tear Us Apart,” or every cheesy horror movie from the late 70’s.

Note that this is NOT a fully-programmable synth; you get string sounds and something that claims to be a piano, and that’s it. (The piano is just kind of a short analog ‘donk!’) You can’t make it sound like a Moog. You do get a few rudimentary controls that let you mix up the tone and dynamics of the strings. If you want to get really freaky you can split the keyboard for strings on one hand and “piano” on the other – it’s paraphonic, so you can play as many notes as you have fingers. There’s a socket labelled ‘Gate’ but I’ve never tried to use it to control anything.

While it does power on and make sound, the pots are a little scratchy and none of the ‘G’ keys trigger a sound. Each of the analog voices is on its own circuit-board inside the synth, so I imagine the ‘G’ board has something wrong with it, but I couldn’t say what. I do have a .PDF of the service manual if you want to have a crack at fixing it. (Hey, if you write everything in C# you never have to play a natural G anyway, right?)

Bonus: this is one of those funky old synths that folds up into its own carrying-case. Neat!” Link
