Adjusting the speed on a BeoGram 6500
After replacing the capacitors and belts and lubricating the mechanics, I measure the speed over a long run to make sure it's right. This BeoGram 6500 was running at 31 and 43 rpm.
The speed is set with two trimmers on the control board, R34 for 33 rpm and R32 for 45 rpm, reachable through small holes in the lower left corner of the cabinet. As the service manual specifies, 33 rpm is set first.
The service manual lists R32 as 47 kΩ, but every board I've seen uses 22 kΩ. If one needs replacing, a CA9V series trimmer fits.
After adjustment, both speeds held steady over the long test.

Replacing the electronic components in the BeoGram 7000
The electrolytic capacitors in the BeoGram 7000 and its 59xx siblings have reached the end of their life. I replace them on the control board, power supply and motor board, along with the rectifier diodes.
Adjusting and lubricating the BeoGram 7000
After the electronics, the BeoGram 7000 gets new belts, fresh lubrication and a full adjustment to the service manual.
