Re: Technics SP10 mk2 - no electronic brake...

Thank you. In retrospect, it was in vain, because I have a "normal" (non-BBC) Logic board slowly winding its way to me (from Malaysia of all places). I want to get rid of the external control box (SH-10C) and replacing the logic board seems to be the easiest way to achieve this goal. I als...

Re: Technics SP10 mk2 - no electronic brake...

How do I check it? :) I know that the mechanical brake engages perfectly (I can hear the solenoid clicking and the platter stops immediately), but how can I check if the electronic brake engages?

The symptoms are as following: the turntable spins up and locks speed, but if I switch from 45 to 33 or from 78 to 45 or 33 it slowly ...
