“For sale is a rare vintage Yamaha TX802 FM Tone Generator. It’s tested and working. No cartridge is included. The only issue worth mentioning is the backlight is out on the screen, as common for these old units. You can still read the screen just fine, but it doesn’t have a bright green glow to it. This is like a rack-module version of a Yamaha DX7mkII. There are 128 preset and 64 user patches, 16-voices of polyphony and six digital FM Operators, with full 8-part multi-timbral operation for key mapping and/or sequencing.”

It does need a battery door and a few of the keys are delayed some. It will also need the internal battery replaced so I don’t know how much of a role that is playing. Because I’m not an expert at these older vintage synthesizers, I do not know how this board fully functions. For these reasons I’m selling it AS IS FOR PARTS OR REPAIR.

Yamaha TX816

“This unit was professionally serviced. Each of the 8 TF1 modules has had its battery replaced and patches reloaded and had its electrolytic capacitors replaced as a future-proofing measure. As is very common with TX racks, the power supply will sometimes emit a high pitched tone. This does not come out the audio outputs so it can still be used for recording like this. This is a well documented issue with this model and even happened when they were new. If the high pitch bothers you, someone sells a replacement power supply. We may be willing to install one for you if you’re willing to pay for it plus labor – message us to discuss before buying.” Click here to visit listing on eBay

Yamaha DX7

“A classic keyboard from the 80’s. I bought this about 20 years ago, and it was pretty much in the same condition then as it is today. A bit of the brown paint has worn from the casing, and there are a few scrapes. All issues are shown in the photos. The side panel on the right hand side is broken at the back, as can also be seen in the photos, and a couple of the higher white notes are slightly damaged. These is the only real bit of physical damage on the unit. I have seen replacements for these for sale on eBay. The lowest white note on the left hand side (C) does not work. It presses down fine, but doesn’t trigger any sound and doesn’t send any midi data either. All the other keys are fully working, as are the screen, the number display and all the buttons on the front. The MIDI in and MIDI out are both fully functional, as are the mono OUTPUT socket on the back and the stereo (mono L/R) PHONES socket on the front. I don’t know about the other sockets on the machine as I don’t have gear I can plug into them to test them, but I don’t see any reason why they shouldn’t be OK too.

When i fired this up for the first time in a while recently, a low battery message was displayed on screen briefly. It has not reappeared since, so I think it was just because it had been off for so long (more than 5 years). I would rather leave it as it is, and leave the winning bidder to replace it if they want as I don’t want to break anything by opening it up. Also, I know that sysex and MIDI generally can be a bit of a daunting pain, so I have reloaded the factory presets and sounds. These will stay in memory just as long as that battery has life.” Click here to visit listing on eBay

Yamaha TX816

“This TX816 I bought from a retired Oberlin Collage professor who had it modified by Robin Whittle in Australia back in the 80s. The modifications (pictured) were meant to give the audio more head room and all 8 modules got this modification. I don’t know anything else about the mods and have nothing to compare the audio to but that it sounds great to my ears.

This unit is fully functional and all 8 batteries have been replaced with new ones about 2 months ago. It has been reloaded with all the sounds it came with from the factory. I’m not interested in ending this auction early and would like to see where the bidding ends up. Thanks for looking.” Click here to visit listing on eBay
