Now that the Workbench Beogram 8000 test setup has a three-pin connector in the platter drive harness for swapping speed sensor assemblies I can give that a try.
Here is the Workbench Beogram 8000 speed sensor assembly being swapped out with another assembly sent to me for testing.
The speed sensor assembly test candidate was taken out of its P4 wire harness and still has its P4 contacts. The owner should be able to re-insert them when I send back the tested speed sensor assembly.
In this case the mini-grabbers attach to the wires from the speed sensor assembly being tested.
Exercising the Beogram 8000 Play function with an empty platter I observed the Beogram search for a record while changing from 33.33 RPM to 45 RPM (as expected). The speeds locked in easily so I think it is fair to say this speed sensor assembly is good.
I was curious as to how this other speed sensor assembly looks compared to the speed sensor that belongs to the Workbench Beogram 8000 turntable.
For that check I re-installed my Workbench BG8000 main board assembly. That is because it is wired with probes for the sensors. I wanted to use my oscilloscope to capture a picture of the Beogram 8000 speed sensor assemblies at work and see how they compare.
1. Position Sensor 1
I have one image for each sensor assembly at 33.33 RPM and 45 RPM...so a total of four pictures.
I arranged them together on one image so I can align the images to compare the speeds.
That is another measurement I will start making on these Beogram 800x turntable restorations so I can compare them from turntable to turntable.
I am declaring this speed sensor assembly sent for evaluation is good.
