MR816X endless encoder

Hi All!

I’ve recently obtained two MR816x’s from a local sale. One of the units has a sheared shaft to the encoder which impairs me from doing any adjustments with the unit. I’d like to repair the unit. Could you please point me in the direction of the replacement encoder? Thanks.

I’m also looking for replacement knobs for the encoders as well.

I have downloaded the service manual but, it seems that the encoder isn’t listed.
