“Selling my NON-working Waldorf XT. It lights up intermittently but does not sound. This is the model that is expandable to 30 voices per the photos of the inside board. It looks like someone plugged it in with the wrong power supply or something as seen by the photo near the input. From what I have read this seems fairly common and repairable but i make NO claims that it is, therefore selling for parts only. I do not have the knowledge or expertise to attempt repair. Sold AS-IS. Let me know if there is anything else you need. Selling it with the non-original power supply. Potentially the problem exists there as well. When I plug it into another correct amp power supply it lights up every time normally but the led characters do not show anything. Otherwise, there are some knobs that the top caps are missing and a minor bend near the lower left rack hole. “

“PAIA Electronics Phono Pre 9802 with rack and power supply. Was working when I used it a few years ago, don’t have access to a turntable for testing today. LEDs light up when the power is switched on.”
” Selling my barely used Teenage Engineering OP-1 synth, fm antenna, soft case.
“I am offering a Preowned Vintage Akai AX80 1980’s Analog Synthesizer. Please understand that it is being SOLD AS IS WITH NO GUARANTEES AND NO REFUNDS. Also understand that this is a very large item and shipping costs will reflect this. I have no control over shipping costs. Here is what I know. The unit powers up without issue and produces undistorted sound. I was able to produce different sounds by adjusting controls. Pitch bend works as it should. I was never able to affect sound with the modulator wheel or the master control knob. One key is broken, but still produces sound. Another key, “A”, is depressed and doesn’t spring back. It does not produce sound. The following, “D” note does not produce sound. Some of the keys had been written on with a marker. I removed most of it with some remaining. I believe it will all come off with additional effort. The tone knob is missing. The exterior in general shows scuffs and scrapes/scratches. AGAIN, THE PIECE IS BEING SOLD AS IS FOR PARTS OR REPAIR.”

“Like new Future Retro Orb sequencer. Comes with power supply and manual.
“The EML-100 is the rare blue faced precursor to the EML-101. Disassembled, cleaned inside and out, fully refurbished by a vintage synth specialist with decades of experience, systematically tested over a long period, working great and sounding incredible! This restoration process – an attempt to future-proof this instrument so it continues to work well into the future – took 30 hours of skilled labor. Few sellers invest the time, love and money we do in the preparation of our gear, and this is reflected our prices.”

” Akai VX90 rack mount synth. I picked this up years ago with the intention of having a play, but never got round to it. I have to list it as untested as I stupidly threw the power cable out in a recent studio cable clear out. It worked when I first got it. I’m including the sampler link cable.”
