Revox HS capstan motor differences - Lpr35 - 25.08.2025
Hello all .
Someone can say me the difference among the hs motor Revox 1.021.165 ( for A77 ) and the model 1.021.302 ( for B77 - PR99 ) ?
The model 1.021.302 can be put on A77 ?
Thanks.

Hello,
I am not 100% sure how it is about the HS motors (never had one on hand), but on the normal version the capstan shaft on the B77 / PR99 is around 5mm longer compared to the A77 version.
PS: I never did it, but I suspect B77 shaft maybe will work on A77 (ofcourse the cover will be not mountable), but the opposite A77-> B77 will not work definetely (capstan too short)
Best Regards,
Tihomir
