The equipment dated back to the 1970’s and was made in Japan and we had no service info for it. It had numerous pcb cards in slot mounts and I guess the drivers were on one or more of the cards, which we didn’t keep.

The geared motors don’t have makers name on them but I found out that they were made by Sanryusha Co. Ltd, and are types P43G; 12V, Steps: 24, Coil Ohm: 70, G ratio: 1/50. The torque is quoted as just 0.3Nm. Their website is in Japanese only and Google fails to translate the bits I’d like. I’m still looking on Google for the other motors which have terms Astrosyn, Miniangle and Shinkoh on them.

Thanks for the info on the RS driver.
