We have only a handful of parts left for those two systems in question.
So, there is a high risk that the system can not be repaired anymore.
Of course it would make much sense replacing the unit with a new device. The new device will give again best performance and warranty, as well as availability of spare parts.
I think it would make sense replacing such old systems with new ones.
By the way, we offered USYS 20 – ODAC 15XY to them! How does it look with a possible order there?
Any news about this project?
