*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. Parts are priced by 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. 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. 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 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.

BEFORE CALLING (719) 964-7205
OR EMAILING parts@oaktreevintage.com

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

a) You have searched 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, we don't)
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'.
SUBJECT lines left empty, or with 'single word' text like;
"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'.
(Subject lines left empty show up as "No Subject" and are deleted automatically
by our anti-spam settings"
