"This unit was most likely the last unit built by the company which was called Technical Research Institute, Inc at the time it was manufactured. Orchestrons were formerly built by a company called Viking, and prior to that, they were called VAKO. The extremely brilliant and talented former Moog sales rep David Van Koevering started and operated the three companies, all of which existed within three-four years of one another and were basically the same company with different investors.
There were two or three odd one-off prototype models (model X for example) that were never fully realized or fully functioning, however this super rare Model Double D was actually a Standard Model and fully realized. It is also perhaps the most usable and reliable model, and only two are known to exist that were made under the Technical Research Institute Inc label. There was one (not as nice) made and labeled VAKO (built for the band America). This particular example I am offering was never sold by the factory as the company dissolved soon after its completion and this unit remained in limbo while the company was dissolved. It has also never been played or used by anyone. Its retail price in 1976 was $7,000. I own and have owned many Orchestron instruments. The Model D versions are the best designs and any double drive / double keyboard Orchestron is especially useful. This unit is the most desirable and rare of all Orchestrons built and it is literally new old stock. The unit has sat unplayed its entire life and may require some tweaking and general servicing. It is being sold without warranty or statement of operating condition. Sold in “AS IS” condition only with NO RETURNS BEING OFFERED.
Fortunately the wonderful Pea Hicks at optigan.com offers remastered, remanufactured disks of all original 8 Orchestron sounds plus 6 additional sounds (14 total). Unfortunately some of the remastered disks are already out of production, however for $100 each I will agree to sell one new copy from my collection of any or all of the 14 remastered disks to the buyer of this unit. I have already had a crate made professionally (see pics) which may be useful for transportation. Anyone wishing to have the unit freight shipped will be offered the unused crate for $375 in addition to the purchase price..."
