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! You are bidding on the set of three kits, not individual items. Happy bidding!” Click here to search for synths on eBay

Teenage Engineering OP-1

“Teenage Engineering OP-1 Keyboard Synthesizer. Condition is Used. Shipped with USPS Priority Mail.

Sad to see this girl go but unfortunately it’s time for us to part.

She is fully operational, the external speakers and jacks are all in working order. Everything on the inside is in shape and is tested!

HOWEVER, there are a few cosmetic dings, see the close-up photos. The only few things are that the protective film on the digital display seems to be peeling and the blue knob is loose, but still works. There is also a burnt image on only certain screens, like the LFO select screen illustrated above.

Again, the machine itself is still the incredible all in one wunderkind machine, but just a little rough around the edges! (which is reflected in the price 😉 )

Comes with: TE Op-1 (used) and Teenage Engineering cable” Click here to search for synths on eBay

Moog Source

” Moog Source Vintage Analog Synthesizer.

Physically, it shows about as much wear as you’d expect for a synth of its age. There is metal rubbing on the back form where it sat in the keyboard stand – the wooden sides also show plenty of wear – but I suppose served their function in protecting the keyboard, itself.

The push-membrane works just fine. Unfortunately I don’t understand how to make everything work. I have absolutely no clue on how to test the sequencer or how to save a patch. I was able to get almost everything working in the video – and anything I couldn’t could easily be because I don’t know HOW – or perhaps there is something that actually DOESN’T work. I hate to limit the sale price of the synth, but without enough knowledge I can only show you what I was able to figure out.

Here’s my best assessment – I was able to get everything working – with the following exceptions: (1) I could not get the modulation wheel to change the sound – and (2) I literally have no idea how to test the sequencer. I wish I could so I could say “I know it works” – but I don’t know how.

Only other thing I’ll add is I tested the ADSR buttons after I shot the video – those DID change the “envelope” of the sound (how fast the sounds started and how long it sustained). I would say the THIRD item I didn’t know how to test was how to save a patch. Here’s what I tried… I tried to hold down “SAVE” while pressing one of the numbers – and that didn’t seem to do it. I read I was supposed to leave it plugged in for some time to let the battery charge in order to take care of memory functions, but I lacked the time before needing to list this. If I am able to of perform further testing this week, I will. ” Click here to search for synths on eBay

Roland AX-Synth Keytar

“There is no wear on this instrument and all buttons, keys, and electronic jacks work. The battery compartment is not corroded + still has its cover and other than one or two light scratches, this instrument, and its case, are in perfect condition.

COMES WITH HARD CASE (with 2 keys), OFFICIAL ROLAND POWER SUPPLY, INSTRUCTION MANUAL/CD, AND STRAP (all items pictured).

I bought the power supply, guitar strap, and hard case after purchasing the instrument as the original seller on reverb did not provide any of these items. I bought this instrument around two years ago for personal use and have not played it much, so I am currently selling it to raise funds for another instrument I plan to buy.

Does not come with stand. Requires a standard instrument cable and amplifier to play.”

Roland JX-3P

” This was a great find. The woman I purchased it from had purchased it new in 1984 (I believe the actual production year is 1983) to “learn how to play piano.” Ironically, this model was the first polyphonic synth I ever owned.

She played it occasionally for a few months, and from that point forward it sat on a shelf in her basement. The only thing that stands between this instrument and a MINT rating is the scuffed paint on the underside of the keyboard (perhaps from being moved across a rougher surface; shown in pictures) and a couple of VERY faint scratches (which I was unable to capture in any images). Overall, I think you would be hard pressed to find any instrument 35+ years old in better shape than this without it being in a factory sealed package.” Click here to search for synths on eBay

Roland Alpha Juno 1 Project Machine

“**Please note this synth has a few problems**

I have had the Juno 1 for best part of 25 years. It is showing some wear and issues are

two keys are not working, one of the keys also does not spring back as it should. The octave up and down buttons do not work and the volume slider is scratchy when being used (its stable once set)

The synth itself plays fine. All the soft touch buttons work and screen is good. Personally I have never had it repaired and use it as a MIDI sound module to get all those classic Alpha Juno sounds, if you did want to repair it the issues seem to be mechanical rather than anything else, I would expect them to be cleaning of contacts but I am no expert. ”

Roland Alpha Juno 1

“Roland Alpha Juno 1 Analog Polyphonic Synthesizer – 80’s Vintage – E120. Condition is Seller refurbished.
Ive cleaned it all up, and the sound is as fresh as it was back in 87. The only flaw in this amazing retro synth is , when i found it and purchased it, it didnt work. I traced the problem eventually to a bad power cable, i looked but was unable to find a proper power cable for it, so i removed the bad one, and soldered in a new power cable. It works perfectly now, amd sounds fantastic. I would keep it, but im already overloaded with equipment in my studio, and just would not be able to give this lovely lady the attention she deserves. Buy it today, ill ship it out to you as fast as i can. Run your fingers across her ivory, and if you play her just so, I swear You can still feel , and hear echoes from the 80s. Give this lady another chance to sing again, you wont be dissapointed!” Click here to search for synths on eBay

Korg Polysix

” Up for your consideration is a Korg Polysix in working order.
I am offering local pickup ONLY for this. I am in Anaheim, CA 92805. That’s 40 minutes southeast of LA.

Cosmetically it is in pretty nice shape. (see pics)
I say working order, but it DOES HAVE TWO MINOR QUIRKS so please read carefully:

1: MG (aka LFO) has a half second delay before effecting pitch, amp or filter, even when LFO/MG delay is set to zero.
Pitch modulation works as normal if you use the mod wheel. Not sure why it does this.
2: Two keys (see last pic) are not responsive. You can take a shot at cleaning the key conatcts or replacing those key contacts. It didn’t really bug me because it was only those two keys.

Aside from those two things, it sounds and looks beautiful. I did everything I could to make this synth work great again. Just a couple months ago, The KLM-367a board was replaced with a clone (NO MORE BATTERY ACID), and my tech went over the rest of the synth and repaired some outputs, fixed some grounding issues, replaced some fuses, and did some other minor things. I always keep my receipts for repairs, but I cannot for the LIFE of me remember where I put the receipt for the work I had done on this one… so I took lots of pictures of the inside so you can see what we did. Hope that helps!

Cosmetics:
Faux-wood sides have some dings, the right side has a couple little bites taken out of it, but it’s not too noticeable. One of the inside hinges was replaced with a screw, and one screw that holds the mod wheel in place is missing, though it is still solid. I went to the hardware store and replaced the four bottom screws that attach the metal faceplate to the synth. ” Click here to search for synths on eBay
