Any opinions about what the general VTA setting number should be with the TNT Hot Rod and Helikon cartridge?
Give Harry a call, he may have experience with the combo. What looks close to you? Do you know anyone with an oscilliscope?
how many spins have you put on your dial?

it is a tough one, i will say that my tonearm is set to slightly high at the back and can get a little bright on thinnner vinyl if it is not adjusted downward.

rule of thumb, get the bass quick and light and if the highs are not too bright then it is likely set within a half dial (50) of ideal.

remember it's all about what you hear
