synchros

Lot: Six Synchro transmitters/positioners, resolver, servo preamplifier, NEW IN BOX

Your tax dollars at work: these pieces of finest aircraft equipment cost the federal government over 11 THOUSAND DOLLARS ($11,471) to acquire. (and I have official documents to prove it, will send copies to you). Then for some reason they decided not to use them and I bought them at an obscure surplus auction. Next time you fill out your tax forms, remember these expensive high precision synchros.

See pictures below.
What is being sold:

6 synchro transmitters (positioners) for precise positioning. The dials are calibrated to 1/10 of a degree of angle. These are precision dials, a full turn of the knob turns the actual dial by only 10 degrees, not 360. Each cost the feds $1,185.00.

All these parts somehow are associated with Litton Poly-Scientific. Call them if you would like, suppliers like this are often surprisingly friendly.

Please check this mirror of this auction for updates. Specifically, I will be posting documentation and PDFs, if I can find any.

These items are new in original packaging(new old stock). I opened some of the antistatic packages to inspect the goods, but did not open the inner packaging. One synchro came opened, but it is new and unused as far as I could tell. The resolver was opened but packaged. The controller was new but open.
