working on my six turntable projects I am always puzzled by small exchanges, in this case by improving the motor system of my Caeles/Allnic 5000 system.
The Dual motor was adjusted to precise calibration on the two speed modes 33 and 45.
It helps a lot as we all know a good and precise motor is the basis of a sufficient turntable system. Now i can adjust efficiently the speed evolving the air driven platter.
One more step to heaven is the following implementation:
Two Sperling motors driven by a forerun tape monitored with a Sperling controller do allow the finest control in two different steps for each speed.
The Sperling motors are set up on wooden Panzerholz platforms taking up each of the three feet being placed on a round granit stone. There is no movement at all thus allowing me to say: I am fully convinced at the moment that the shown configuration with the two Sperling motors driving the air based platter via the H 5000 DHT Allnic phono preamp it is definitely my best turntable system in 2018!
