*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.

ATTENTION! ATTENTION! ATTENTION!
FIRE DANGER!!!


Above right are photos of B&O / Bang and Olufsen S-75 speakers that have their crossovers burned to a crisp, and oddly still function to a fair degree. We have seen this on a couple of other pair. We have purchased about 4 vintage / original pair over the last 12 years. One pair for ourselves. The first pair we purchased years ago, I have personally. The next pair, did function, but we found their sound was slightly different, one from the other after some CAREFUL and DETAILED listening, side by side with pink noise. After testing all the drivers independently with no appreciable differences, we decided to inspect the crossovers. That's when we were amazed to find charred wires, touching each other internally and burned / melted components. This was likely due to the speakers being connected to amplifiers / receivers that were capable of producing much more output current at 4 ohms than most B&O receivers and obviously connected to receivers / amps that were much more power than the speaker were designed to be use with (operator error, and in no way sheds negative light on B&O speakers). Most vintage / original B&O speakers are rated at 4 ohms, and at 4 ohms, most amps are capable of producing their max current into only the one pair of speakers.  Don't ask me how the drivers still functioned connected to those crossovers. We parted them out and didn't think anything else about it, other than how someone had so overpowered a speaker as to "flame" the crossovers. Then the next pair that came in had similar symptoms. We had forgotten about the crossovers on the first pair, and did all the tests again. We then pulled the woofers and found even more badly burned crossovers. At this point I inspected my personal pair, for fear of a fire hazard. Mine were fine, however I am going to replace the very flammable wool, hair, shredded cloth internal batting with non-flammable insulation. The forth pair that has come in has the same problem with the crossovers. According to our math, that's a 75% failure rate! Just FYI when you're out there buying speakers from the "wanna-be's" on the auctions, saying that their "speaker tests fine" and is in "mint condition". Yeah, right...
While we have seen crossovers in other brands / models of speakers damaged due to overpowering, overheating, abuse, accidents, it's typically evidenced by exploded capacitors or broken / burned traces, or fatigued solder joints. We also see coils that have come loose from their moorings, but never anything this catastrophic. This is only a problem we are aware of in the original / vintage S-75 models, but it may be known in other models as well.
This is not a slam on B&O speakers, but a warning as to their 'mis-use' with amplifiers that are too large, or certainly larger than they were designed to be use with.
The B&O, S75's are great sounding speakers by design when used correctly.

NEW INFORMATION: Since originally posting this we have received numerous phone calls from recent buyers of not only original  / vintage 1970's S-75's, but S-30's, S-45's and S-80's (S-80's are 8-ohms) alerting us that they have the same issues. Virtually none of them knew the history on the speakers, but you can guess they were all connected to a power source that was pushed beyond the capabilities of the B&O crossovers.
