Yamaha TG33 Project Machine

“Yamaha TG33 Vector Synthesizer. 32-note polyphonic/16-part multitimbral synthesizer that uses AWM and FM waveforms to produce some pretty amazing sounds when paired with the four-quadrant vector synthesis. It may look like an answering machine, but it produces some serious ambient soundscapes. The unit does function, but there are some issues with the output. The headphone output functions fine, the first set of outputs has a bit lower output level and the second set of outputs is even lower. I admit that I really haven’t read the manual, but I did jog through some presets and also pop in some sounds in the four quadrants for some vector synthesis fun, but it really doesn’t fit into my workflow, which is modular based at this point, and I’m not that handy with fixing electronics. It could be used as is, but were I to keep it, I’d want the output levels a bit higher. I’ve seen discussion of this online so it’s a common issue with a number of solutions, but not in my wheelhouse”

Sequential Circuits Six Trak

“This sale is in aid of my local Hospice Thrift Store, where I volunteer working on electronics. I sell items here for the store that don’t readily sell in house, alongside my normal vintage audio business.

Along with the more routine items that the generous donors contribute is the occasional gem and this is a fine example, a Sequential Circuits Six-trak.

I’ve occasionally dealt in synthesizers over the years but never had the pleasure of checking out an analog synth of this level. Fortunately the manual is available on line and I’ve checked every control and display, checking tuning, level controls, polyphonics, parameter change (I had a lot of fun with the glide parameter set to max and the arpeggiator), recording and playback, including getting two tracks recorded and playing back simultaneously. Audio output was clean.

I haven’t checked the midi functionality and offer no warranty in that respect, however you may draw the conclusion that a full check out as noted above makes that low risk. If you are local, I’d be happy to arrange for you to check out midi yourself BEFORE purchase.

This will be shipped carefully packed using closed cell foam (not expanded polystyrene) to secure and protect the keyboard.”

ARP Odyssey

“Vintage ARP Odyssey Mk II. Model #2813. This synth is fully functional with a couple of caveats. First, a few of the sliders are a bit sticky. Not terrible, but you feel a little extra resistance when you push them. Second, there are three or four keys where the duophony can get squirrely. Everything plays fine if you’re going mono, but a couple of j-wires are slightly out of whack, causing a little weirdness when you play two notes at once. This synth sounds amazing, plays very well aside from where noted, and looks really good too. There is a blemish on one key, and a small amount of wear and tear, but it’s a really fine example of a black and gold Odyssey. Fresh key bushings as well.”

Powertran Transcendent 2000 Project Machine

“Rare Joy Division sounding Transcendent 2000, not in currently working condition. The unit was in transformation to being made into a rack model from a keyboard, since 3 of the keys do not work. Photos of the keys are included and the power cord was removed to install a 110v power supply for use in the U.S. You can continue to work on it for a rack or desktop model, and that would actually be a beautiful synth.
It worked find otherwise, and 3 keys got damaged in the transit, so I searched the internet of a gent in England who turned his keyboard model into a rack for portability. You don’t really need the keys if you install a midi panel and use a modern keyboard controller.
Anyway, this is the job for someone to continue working on this already made kit when it was purchased, or use it to enhance your already working Transcendent 2000 for parts. Either way it’s worth it!”

The Harvestman / Industrial Music Electronics Iron Curtain Electronics System

“For sale is the complete Iron Curtain Electronics analog synthesizer system by The Harvestman/Industrial Music Electronics.
All eurorack modules are in very good condition. Includes original packaging. Powered skiff not included. Ships to lower continental U.S.

Manufacturer’s description:

The IRON CURTAIN ELECTRONICS system is a faithful recreation of the analog circuits from the famous POLIVOKS synthesizer. This project was completed in cooperation with the Polivoks designer Vladimir Kuzmin. The included modules represent the full Polivoks feature set, all-analog electronics with the use of original Russian components where appropriate. The authentic sonic character of the instrument is present and verified by the designer. It’s the antidote to the ordinary analog synthesizer sound, suitable for industrial applications.
This is a full synthesizer instrument ready for recording or performance. Just add a keyboard or sequencer.
Included modules:
2x Polivoks VCG saw-core oscillators (saw, tri, PWM outputs with octave switch and linear/expo FM. Tracks 1v/octave.)
1x Polivoks VCF (Distinctly aggressive 2-pole filter with low- and band-pass outputs. Thick bass distortion and screaming resonance.)
1x Polivoks modulator (Russian transistor noise source, utility LFO, sample-and-hold.)
2x Polivoks VCA/ADSR (Combination module with looping ADSR envelope and vintage-style VCA.)
1x Lider Suboctave (A unique octave effect that sounds like the original signal, not a square wave.)
1x King Slender mixer/slew

1x Malgorithm mkii (bonus module: voltage-controlled bitcrusher)”
