My Beogram 4002 fluctuates at 33 rpm
It starts out perfect but after approx 5 minutes speed starts to fluctuate (goes down in speed)
Everything else works fine on the 4002, I have changed the drive-belt a year ago due to other issues, but it didnt remove the fluctuation at 33 rpm
Help?
Looking at circuit resistor for setting 33rpm, can not see part number and pre-set resistor 1R15 should be looked at first, then relay 1RL1 contacts. The resistors mentioned above will need a small amount of switch cleaner and move the adjustment to clean the contacts, If that is not a cure clean contacts on 1RL1 . If you are unlucky 1R15 will need replacing. Others may know of more obscure fault. I have never seen one of these players.
PS Might be worth cleaning 1R14 (45rpm) pre-set and 45rpm pot adjuster while you are there.

Hi there. Welcome 🙂
First things first, replace the speed trimmers.

Yes.
Then the speed switching relay.
And finally, clean and lubricate the motor bearings.
