*Note about parts sales

* Our "parts units" & parts are primarily archived for the purpose of restoration / repair of "Oak Tree Vintage" units first. Only if we do not have a "viable" unit in yet, either already in process or in line to be processed, that may potentially need parts from a "parts unit", will we release available parts for sale. As many of you know, the restoration of a unit can be a long, time consuming process. We may "lock up" parts that we may potentially need in the restoration of a unit. The parts are valued by the "potential value" of the unit they can be applicable to, time to extract, their rarity & condition to name a few criteria. A non-response to an email request for a part (we may have), likely means that we are still determining which parts we are going to need for the restoration or repair of a unit. Again, the parts are first for the restoration of our units and secondarily for the public market. Since we list the parts available for ourselves, it is not much effort to modify the menu's for web publication. Frankly, publishing them to the web, in many instances, makes it easier for us to determine if we have the part for our needs as well. The alternative would be to not offer them at all to the public, however most parts are always available to the public for sale. Thank you for your understanding.

NEW
YAMAHA DX-7
INTERNAL MEMORY
BATTERY
for sale
We have these custom made for us and are designed to be direct replacements for DX-7 batteries. If your battery is older than 5 years (and most are 20+ year and running on vapors) then you need one of these. It's not a matter of "if" your battery will cause your keyboard to fail, but simply a matter of "when". Yeah, I know you've heard that before, and you still waited till the part failed / broke at the worst time, and you'll probably do it this time as well, but you've been warned.
Recommend installation by qualified technician and you will need to re-install the internal memory from an original data cartridge, another DX-7 or similar device, or off the web!

"
SOLD or SOLD OUT"
please call
or email for it.
