Dear Sir,
We have a Contraves 53-M1 table with an Ideal-Aerosmith 4000 controller. The middle gimbal's precision is around 32 arc sec which is quite a bit higher than the specification of 1 arc sec. It was within spec when we purchased the table refurbished approx. 1.5 years ago. Ideal-Aerosmith does not know exactly what is wrong with the table. Would you consider looking at the table and providing us an estimate for repair?
