*Note about parts / spares sales

* Our "parts units", parts / spares and related reference information 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 (even though they may appear as available for sale to the public). 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 (and not necessarily get it marked 'Hold' or 'Sold' on the site right away). Parts are priced according to the "potential value" of the unit they can be applicable to (meaning the amount WE would be willing to pay for the part if that was all that was standing between us having a "shelved unit" or a valuable / sellable unit), time to extract, their rarity & their condition to name a few criteria and likely will be completely unrelated to the original cost / price of a part when it was currently available from the manufacturer.

Parts Photos; We get a number of requests for 'photos' of a specific part. Unfortunately, in most cases that is not practical as the amount of time involved in posting that exceeds the value of the 'unique' part. We will sometimes post photos of less 'unique' parts, if there is a greater chance of them being available in multiple quantities, or on a more 'repeat' basis.

Shipping: Shipping on most 'small' parts if typically via Postal first class or Postal Priority for both domestic (USA) and international orders. Larger parts such as transformers and drivers (speakers) are typically via FedEx gnd.
Some parts sales such as those for empty 'speaker cabinets', empty 'component cabinets / covers / bonnets' and 'speaker grills' are 'doomed' from the start. Due to their size and required packing supplies, the cost of 'packing for safe transit' and shipping are typically nearly equal to and sometimes greater than the cost of the part.  Think about it. An empty speaker cabinet or stereo receiver case is essentially the same size as a complete one. Yes the weight will be less, but most of items that size are calculated on 'dimensional weight', not actual weight. Secondly empty component cabinets have to be packed to disallow breakage, typically requiring nearly as much packing materials as an entire unit. Speaker grills have to be 'sandwiched' between foam sheets in large, custom ordered boxes (all relatively expensive).  It is what it is....

A non-response to an email request for a part (we may appear to have), likely means that we are still determining which parts we are going to need for the restoration or repair of one of our units. 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, which in turn makes the reference information and occasionally the part available to the public. 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 to all of the above would be to not offer them at all to the public, however most parts are available to the public for sale.
BOTTOM LINE IS; IF YOU DON'T SEE IT AVAILABLE FOR SALE, WE DON'T HAVE IT!
 Thank you for your understanding.

See sales banners on parts pages for details







Most of these components are "take-outs" from units that for various reasons we 'chopped' and unless otherwise noted are in serviceable / working condition / shape!
   In the case of output transistors, they will be tested / checked prior to posting and once again prior to shipment, pots / switches will be 'cursory' cleaned, parts already missing / utilized from circuit board will be noted, transformers will be checked prior to posting. Filter capacitors  will be tested / checked prior to posting and once again prior to shipment and 're-conditioned' / 're-formed' if necessary.

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!

*When we say "some parts MAY also fit", that does NOT mean ALL the parts listed 'WILL' fit, and unless we show specific info that a particular part DOES 'cross-pollinate', do not infer that it does or will fit. Only careful research and comparisons, on YOUR part with service manuals MAY indicate a POSSIBLE substitution. If your situation is 'critical', do not base your decision on information found on this or any other page of this web site and do your own research.

~9:30 AM- ~7:30 PM most days COLORADO / ROCKY MOUNTAIN TIME ZONE

We DO NOT have your part unless the following conditions are met:

A) You HAVE SERCHED our page(s) and HAVE FOUND the part you are looking for SPECIFICALLY listed on one of our pages or you have solid information that it's a 'bona fide' substitution for your part (unless noted already, we won't have any further info along those lines)
AND
B) The part that you have found is NOT marked as SOLD or SOLD OUT.


If you do not see it listed after thoroughly searching the pertinent page
(likely the page you landed on originally),  
we do not have it,   
nor do we know when
it might come in,   
nor do we maintain "waiting lists" for parts,    
nor do we know who
might have it.

Sorry, but phone and email traffic for parts
we don't have listed or for parts that are already marked "SOLD" has become too consuming of time resources.


 We try to keep these pages 99+% updated.
If you don't see the part you are looking for, simply check the web page periodically as we never know what will show up each day. Thanks!!!!!


ALSO: When e-mailing be sure to include a relevant subject, ie: Brand / Model number / reason for inquiry in the 'SUBJECT LINE'.

"Hello", "Hi", "parts", "stereo", "inquiry", "question", "selling" or similar or similar 'un-qualified' terms will automatically be deleted by Anti-Virus / Spam settings or receive 'Low Priority'.
