Yamaha CS20M

“Yamaha CS-20M Vintage Analogue Synthesizer.

Good working condition, everything works as it should and sounds absolutely brilliant.

Rare to find these and this particular model is fitted with the same filter type as the CS-80. It sounds very unique!

A few chips in the woodwork but nothing that really spoils it, just a sign of over 40 years use being the workhorse it is!” Click here to visit listing on eBay

Yamaha DX7

“Yamaha DX7 61-Key Synthesizer Keyboard w/ Case & #3 Cartridge. Internal Battery is at 2.8v

So all the keys work and I went through the presets and all of them worked. The backlight for the display isn’t working. I don’t know how to use the functions. The volume knob works the pitch and the modulation work as well. I think it may need an internal battery but I’m not sure. I’m selling this working for parts or repair due to the light and me not being able to test all the functions properly besides the keys. I don’t want to hide anything but I want you to know that it does play nice and sound good. I took a close up of the chunk that’s out of the back corner. Other than that it’s in fairly nice condition. A little bit of tape residue here and there. The case is solid but the interior padding isn’t super protective so I’m going to add some extra protection when I ship it so it doesn’t move. It will get to you safely. I’m going to wrap the keyboard case and bubble wrap and then put it in a box.” Click here to visit listing on eBay

Yamaha TG55

“Yamaha TG55 Tone Generator rackmount multitimbral synthesiser synth circa 1992 with manual and voice card

Yamaha TG55 Tone Generator synthesiser synth (1992) plus manual and voice expansion card

Multitimbral sample based synth all working properly as far as I can test
Voice layering for rich and complex audio
Stereo and individual output routing for individual voices
240V permanently attached mains flex with UK 3-pin plug.

I used it in the mid 90s to extend my sonic palette and develop my MIDI programming skills.
Unsurprisingly, the available sounds are classic early 90s fare, and as you’d expect from Yamaha, the sound quality is excellent.
I’ve owned it since 1994(ish) and it’s been well used so it shows wear typical for an older instrument. Condition can be seen in photos
The original mains flex was far too short so it was extended to 2m long.
The lot also includes the original user manual and one voice expansion card.” Click here to visit listing on eBay

Yamaha SY22

“Yamaha SY22 Synth w/Road Case & Manual

I’m the 2nd owner of this thing, but I’ve had it for nearly 30 years. It works, but could use some minor repair. Details below.

You’ll need a new power supply. $20 on Amazon will get you a new 12V power supply adapter. The one included(a 10V, but it’ll take 10 or 12) with this has a short in the cable, and works most of the time, but is on its last legs.

As for actual repair needs, there appears to be just one:

The far left key(Low C/the last key on the keyboard) is dead. No sound is generated from this key. I can hear what sounds like a tiny screw rolling around inside the keyboard, so maybe that has something to do with it. Again, I’m not a technician, so I’ve been reluctant to dig into the guts of this thing.

Otherwise, all the sounds and functions are operational. The Vector Control still works great, and makes for some cool effects. It’s a little worn, but still in reasonably good shape, considering the age, and it’s seen almost no action for over a decade, so I think it’s mechanically sound, aside from the issues mentioned above.

It also includes a Roadie Case by Hybrid(probably worth $100 by itself), that’s remarkably sturdy, and still in great condition, along with the original manual. I’ll even throw in an X-brace keyboard stand, if you want it.” Click here to visit listing on eBay

Yamaha DX11

“This is a great synthesizer – what’s not so great is the state of its power supply. Some components on it failed a while back, and I attempted replacing them, but the traces peeled off the board when desoldered. I got the new components in (in a hacky sort of method) and it worked for a while, until it recently bit the dust again and I’m not sure how to fix it! If you have a use for this – take it on!” Click here to visit listing on eBay

Yamaha SY35

“The Synthesizer is in overall good condition and sounds Great! Everything powers up and works properly when tested. There are a few scratches on the screen and case and couple on the keys but overall nothing too bad at all. It could use cleaning and polishing to really look good.” Click here to visit listing on eBay

Yamaha SY77

“Yamaha SY77 Vintage Keyboard FM Synthesizer 1989.

Reasonable offers considered. US Seller. Fast and safe shipping with full insurance coverage over full purchase price.

B+ cosmetic condition.

Some wear from use over the years, but nothing major on the top case.

One palm sized dent on the bottom cover fr the previous owner trying to take the cover off without removing all screws. Still sits flush and this doesn’t affect any functions of the keyboard.

One screw missing from the bottom cover. Plastic threads for screw broke off. Will be included with sale to be reglued in.

Tact switches do all work, but “enter” & a couple of others need a solid press to work. Could just need cleaning, could need replacing. Will possibly attempt to replace faulty tact switches before sale.

Missing (1) plastic slider cap for data entry slider.

Backlight on display non functioning. Display still legible. Planned on upgrading to modern replacement instead of changing backlight.

All keys have been removed and keybed has been throughly cleaned and re-lubed. All keys function as they should and a couple of keys have been replaced due to faulty plastic clips.

Floppy drive has been cleaned with a new belt installed. It is fully functional now.

Internal Battery original but fully functional.

Includes original sound banks along with 64 updated sound banks with vintage Analog type sounds.

Very solid FM synth. Dx7 on steroids.” Click here to visit listing on eBay
