PAIA @ 17 July 2018, Comments Off on Paia 5700P The Drum

“This listing is for one extremely rare Paia “The Drum” 5700P Analog Percussion Synthesizer. It is essentially a cab filled with 4 identical modules that can generate a sound that is suited to percussive analog tones. It can be triggered via any sound source, including other drums, eurorack, a drum machine, etc. (voltage trigger OR audio into the 1/4″ jack). Each voice also has CV in that tracks across a few octaves so they can also be used as a stand-alone synth voice for basslines, melodies, etc. if so desired.
The sound can be described as very raw and weighty, similar to other early analog percussion units like the Simmons SDSV and 808. This unit works very well for it’s age, though some pots/switches could use some cleaning. Because of the age of this piece, it is sold as-is.” Click here to visit listing on eBay

Modular, PAIA @ 12 June 2018, Comments Off on PAiA Modular Synthesizer

” Travel back in time with this vintage synthesizer. I don’t know much about it. The keyboard unit is 37 keys. It is a kit unit. I cannot even figure out where the power switch is, let alone the amplifier output jack. I got it from an electronics engineer who never once used it, who got it from another electronics engineer who apparently assembled it in the 1970s.

Paia Electronics made kit synthesizers in the 1970s. I believe this is a completely homemade copy of a 1970s Paia synthesizer. The builder bought their own components and built and soldered their own circuit boards. I think it might be a Paia 2720 copy.

Unlike the Paia components in the various spec sheets and catalogs included, none of these components have the Paia stamp or Pais graphics, as shown in the literature. Among the literature included are: a 1974 Paia catalog; a 1975 Paia booklet without record; a 1975 Paia schematics symbology booklet; 17 old Paia component booklets with specs (a couple are doubles); a 1972 “Using the Paia 2720 Synthesizer” booklet; and some other spec sheets, including some on clear mylar.

It is truly untested. I plugged it in. I found one button that made a light turn on, but, other than that, I have no idea about it. It was in a clean and dry house for the last decade or so.” Click here to visit listing on eBay

“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.

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.

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.” Click here to visit listing on eBay

“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.

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.”

Modular, PAIA @ 21 February 2017, Comments Off on PAiA 2700

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.” Click here to visit listing on eBay
