Encoders used in Orion XT12g - need info

[JorgeST]

All,

I own an Orion XT12g with a blown motor encoder - my doing of course.  Orion is no help but I found a product from astro-gadget.net that 'might' restore some of the functionality.

A piece of information I need is the one that pertains to the number of 'ticks' per revolution for the encoders attached to each 'axis' of the scope.

Note: I am not referring to the encoders used in the motors (they also have those) which are low resolution but the ones on the axes themselves.

The said encoders do not have an index mark which would the task trivial by connecting to entire contraption a logic analyzer with deep memory. 

I would be very grateful if someone has data on these encoders

I can add pictures if that help.

Thank you in advance
