Helius Orion Mk1

[Robert Onion]

Hi

I’ve just picked a S/H turntable with a Helius Orion Mk1 tonearm

Can anyone advise on how to adjust the counterweights? They seemed to be locked but there is no obvious grub screw etc on the counterweight to loosen??

Many thanks in advance

I had one years ago IIRC if the counterweight is in two halves they lock together, so hold the nearest to the pivot still and rotate the rear one anti clockwise.

It was probably 40+ years ago so may be wrong.
