*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. Thank you for your understanding.
 


Most of these components are "take-outs" from working speaker cabinets 
and unless otherwise noted are in perfect shape! Where necessary foam
 surrounds have been replaced and / or speaker has been professionally 
and correctly re-coned!

If you DID NOT see your Unit or Part
"
SPECIFICALLY"
listed, or the part you are seeking was already marked
"
SOLD or SOLD OUT"
then please
DO NOT CALL or EMAIL for it.
If you do not see it listed,   we do not have it,    nor do we know when it will come in,    nor do we have a "waiting list" for it,     nor do we know who would have it.
Sorry, but phone traffic for parts we don't have listed is too consuming of time resources.

      If you DO see your part listed, and it appears to be available or you know for a fact that it is a VERIFIED-GOOD substitution from a unit or part that we do show, then by all means, give us a call to verify availability and to place the order.
 We 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!!!!!
