Beogram 4002 Type 5513: Speed Test #3 Completed

The third platter speed test is complete on the Beogram 4002 restoration. This test was to check the platter motor speed stability after the Beogram main board was reworked (new capacitors, trimmers and RPM relay).

The result is even more improvement on the turntable platter speed. There were a few spikes in the steady state speed but the magnitude and frequency of the spikes are way less than the first two tests.

The next step on this restoration is the replace the RPM scale bulbs and the Beogram main reservoir capacitor.
