"This is the plastic-body variety, which is allegedly more reliable than the earlier metal-body version. It has been professionally serviced and works perfectly. All filters tune correctly - see photo. I also replaced the internal battery, and updated the OS to the latest V3.5.
Stuff done:
New 2/3AA battery fitted. The proper OEM one, not a button cell.
Power supply completely rebuilt.
Tested and tuned and ready to go!
Replaced a few keys.
Keymapper IC replace.
There are minor blemishes on the front panel - see photos - but nothing major, and nothing on the display.
These instruments really sound glorious and are now starting to appreciate in value. Grab this one while you can!"

Roland TB-303 with Quicksilver MIDI and Carrying Bag

"Has Social Entropy’s Quicksilver MIDI mod installed which adds several functions, I’m more of a Din Sync user so I really don’t need the MIDI one.
Cosmetic condition is good overall for its age and normal use but has two cosmetic details worth mentioning, both details can be seen in the last two pictures, first it has a small chipped corner, it was like that when I got it, second one is that some of the silver paint is starting to fade around the filter and envelope control knobs, pretty normal for a used TB as in those knobs is where the 303 magic happens .
Quicksilver user manual can be found online at social entropy website.
Includes the original Roland carrying bag, the IN and OUT MIDI cable adapters and a brand new power supply which I will take out of the package for shipping ."
