Arm Heighth on VPI Classic


HELP! Have a Classic 3 and just bought a 200gram lp; so, I'm assuming that I need to adjust arm height for the thicker lp. Classic 3 manual says to make sure to loosen BOTH set screws before making adjustment. For the life of me, I can only find the one black knob on the tower. Where's the second one? Do I turn the tower clockwise to raise the arm and how much turning should I plan on?

This adjustment should be done using critical listening. I suspect that such a small adjustment is not worth the effort.
Rockyboy....yes

Hiendmuse....you probably need to raise the rear end of the tonearm much more then parallel. This is a common misunderstanding....try the rear end quite high and listen before setting it horizontal..or even close to horizontal.
Hiendmuse....I know, I know....Harry sets up his arms horizontal, and then listens by slightly raising the rear...but the arms are mainly horizontal. I have a 3D arm - I've been setting up arms for about 40 years, but just recently came across an article on Fremer's site ( Analogue Planet) that intrigued me. The VPI arm is soooo easy to raise/lower that I tried Fremer's suggestion, and to MY ears he is right. I suggest you read the article and try it for yourself...it might change your thinking about this issue too. If you do raise your arm, recheck all the parameters since it might shorten and lighten the arm. Experimentation... That's what makes this hobby worthwhile.
The reason tail down became a popular way to set up an arm was that moving coil cartridges nearly always had a high frequency lift to them that tail down reduced. We all should use our ears to determine the setup of our rigs...but if you want to properly set up the arm Fremmer makes an excellent case for tail up. Newly designed high end moving coils don't exhibit that high frequency lift. I recommend reading Fremmers article, which is also validated by The Absolute Sound.
