Hi guys,
To get these numbers I used the Dr. Feickert Platter Speed Apple App with Adjust+ LP test record playing a typical 3.150Khz pink noise tone during one minute time.
These are my interesting results:
New
silicone transparent belt (replacing the old
rubber black):
Adding the S. Synchro Power Generator:
As you can advice the frequency modulation decrease from +/-8.X Hz to +/5.X Hz, simply amazing how these values have been reduced. Thanks to give to the motor perfect frequency powerline his stability operation increases and the speed accuracy is simply better.
With the SPG I also can play with the powerline frequency Hz trying to get a perfect "mean frequency" thanks to the small front panel screws, e.g. 33-1/3rpm and 45rpm. As you can see in the last picture I got a little bit more than 33-1/3 (undetectable value)
Next post I will talk you about how my turntable sounds now, Wow!!
