Hey, Dan, you are posting in rec.aviation HOMEBUILT. I appreciate your
expertise, but your bias towards keeping large jet aircraft running is
showing. Have you BUILT a homebuilt:? Have you MAINTAINED a single engine
aircraft?

With all due respects, sir, if you have not, please refrain from those of us
who have.

Jim

Every aircraft synchro I have ever seen uses 26 VAC 400 hz single phase.
I have seen power supplies for them on e-bay for around $25 or so. It's
been awhile since I have looked, but they were there. In any event synchro
systems don't seem to be sine wave particular so a simple power supply
should be easy.

If you want cheap aircraft synchros find a shop that repairs jet
aircraft. The 1" "peanut" pressure indicators contain a synchro that
usually outlasts the internal lighting. I have found them on e-bay also.
Compass amplifiers such as used in the C-12 compass system contain a
multitude of synchros since they use a gear train to drive several
synchros. Vertical scale instruments such as those used on C-141 also
contain synchros. I have seen those for sale on e-bay also.
