Did you measure voltages/ripple?
Check for blown/bad caps?
Is servo coil ok? (I think it has one https://www.rythmikaudio.com/technology.html (https://www.rythmikaudio.com/technology.html))

I don't know if this is relevant: https://www.diyaudio.com/community/threads/velodyne-cht-headache.407493/ (https://www.diyaudio.com/community/threads/velodyne-cht-headache.407493/)
