Beogram 4500 tonearm height setting

[Jonathan McCall]

Struggling to set my tonearm height correctly and get it parallel to the pickup sensor arm.
The service manual says to adjust the tonearm using screw B, but I can only get it to a state where I can adjust the maximum height (and get it level with the pickup arm) but it always flops down. To put that in context, I’m lifting the tonearm up and adjusting the height so that it’s level with the pickup arm. Releasing the tonearm it drops down.

Im not sure whether I do this with power on, cartridge in, record in place etc etc the manual isn’t very helpful.

Similarly, getting the tonearm parallel to the pickup arm using screw C is impossible. Screw C seems to be made of plastic and a bit on the fragile side. The tonearm waggles about all over the place, so trying to get it parallel needs me to start in a steady state, which I don’t have.

On a final note, how do I clean the arms – they’re a bit tarnished.

Thanks !

After some tweaking of screw B and getting my actuator rod set up correctly, I now have my tonearm level with with pickup arm and the tonearm height actuator rod (plastic one) operates correctly on the lever to raise/lower the tonearm.

The issue I have now is the tonearm doesn’t raise or lower when I press play. It tracks backwards and forwards correctly, but I think I’m missing something. Does the cart need to be in and the case closed for everything to work correctly ?

Everything back together again and working as it should. Importantly, I didn’t damage the MMC2 – which is a relief !
