Bell 212 AFCS Amplifiers and Synchronizer 'slices'. Basically a component that consists of standard electronic components and a small rate gyro.
These units appeared on the State Depts Contolled Exports list last year and now average approx 6 months delivery time from Bell, including return after repair, of which only Bell are approved to do.
You can still buy surplus/SV units from various suppliers outside the USA, but price has sky rocketed as a result.
Good if you are selling, bad if you are buying
