At the price I see for synchros out there, you might be better off buying
a used standard

The good news is even though that unit is untested, there really are only
2 parts in that unit - the mechanical switch, and a set of multi tapped
transformers (Potted - in beeswax). They either work totally, or not at
all (I worked for Astrosystems for a decade 'back when')
