You're right Lewm in your recollection of JP Jones' skepticism about Victor's Patented Bi-Directional Servo......
And then Hiho (I think) produced all the World Patent Documents for it which floored JP who said he needed to read all the documents to try and understand the principles.
He never reported back...🤔
I don't think enough documentation exists for the significance of Victor's Bi-Directional Servo Control to be appreciated.
It is the exact opposite of Technic's design which utilises a powerful motor with huge torque to control a massive platter.
With the Victors......a lightweight aluminium platter is controlled by a medium-powered motor (sometimes coreless) combined with their various servo-controllers....with the Bi-Directional Controller utilised in their higher models.
I wasn't really floored insomuch as I'd forgotten all about it. Â The patent primarily claims a PLL implementation with less jitter. Â Maybe the TT-101 uses this implementation, maybe it doesn't. Regardless it has nothing to do with their bi-directional marketing copy. Â PLL servos are bi-directional.Â
