*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.

JUST FYI FOR FOLKS LOOKING FOR
 PIONEER
CS-88a & CS-77a

MODEL SPEAKERS.
Pioneer, for some reason used foam surrounds on the tweeters of these 2 models. After 20+ years, it will be difficult to find a pair that still has the foam intact (as foam surrounds generally have a useable lifespan of 10-15 years, depending on the environment they have spent the majority of their lives in). 
Almost 100% of the models we have seen have their tweeter foam rotted. We have only found one suitable "fix" for this and have searched high and low for a 16 ohm replacement for the CS-88a, or an 8 ohm for the 77a, with no success. The fix is if you have a pair that has no, or little visible deterioration, then the matrix can be recoated with a light rubber cement (not paper-rubber cement, and we've tried many that curl the surround and render the driver useless) for years of trouble-free service.



A visibly fine surround, is still bad and will visibly deteriorate after a few songs are played on them.
We see these at on-line auctions often, and in every case the speakers either still have their rotted originals or a replacement tweeter, of some-sort installed. Due to the rarity of 16 ohm tweeters, we have to assume that the replacement tweeters the owners / sellers have installed are of incorrect impedance, which at the least, effects high-end efficiency (volume) & at worst can create load issues for whatever amplifier they are connected to. All this while using the word "Mint" or some similar adjective to list / describe the speakers. 
Again this is only prevalent in CS-77a & CS-88a. It is not a factor with CS-77, CS-88, CS-99, CS-33a, 66a, 99a or 901a's.

PS. We also see a similar problem with many other manufacturers' speakers like the Bose 301, 501, 601 & 901 speakers from 15+ years ago, except for the earliest versions of their speakers which used cloth surrounds. 

Any manufacturers' speaker utilizing foam surrounds (common from typically 1980 thru present) that is over 10 years old should be suspect, but the above mentioned models are almost a given.

PSS. Even though a speakers foam surrounds may "look" fine, they probably are not! Vintage speakers posted for sale by individuals & at auctions / yard sales have commonly not been in use for many years (other wise they probably wouldn't be for sale). In many cases, once you start playing them more than a couple minutes, you can watch the foam disintegrate right before your eyes, just by playing 2 or 3 songs at above average volume levels.

Just FYI while you're out looking.
