No spare parts for the CGE......

Unfortunately, the spare PCB boards for the CGE mount were not received......This evening I carefully studied CGE problems and the electronic design. What worried me is that the specification of the RA/DEC motors is 18ohm, while the driver IC on the control board can continuously drive a load of 600mA: 20ohm. When performing a long high-speed slew this IC can become overheated. It can be replaced by a heavier version that can deliver 1A continously. Maybe that is a better option.
