Sold my TT, getting another

Certainly yes,
You will have problems!
In your place I wouldn't jump so-little since the more little you jump the more mony you'll eventually spend for upgrade.
You will definitely will want to jump to better one.
As to setting up the cartrige, IMHO, you can only do it yourself. It has to be some time before you'll find the best point of listening that consists of mainly three variables Tracking Force, VTA and load. For MM you can drop load but some phonostages may have adjustable load capacitance.

It's as bad as cocaine.

Tone arm is the AudioQuest PT-6
It is the Vpi that was listed here.

You're going from a MMF-7 to a VPI 19 Jr.?! That's kind of similar to selling a Toyota Camry to buy a Honda Accord! He-he! If I were you, I will wait a couple of months, save some more money and get a significantly better table (Nottingham Space Deck, entry level TERES, Origin Live Aurora, etc..). Just my humble opinion... Good Luck!

Scott, you will have no problem setting up your turntable. Although your particular rig was originally set up with a Sumiko Blue Point Special. Your PT-6 tonearm does provide you with a provision for adjusting VTA. You may want to adjust VTA accordingly with your new Grado. Grado's are extremely sensitive to VTA. I use a Grado with a RB900 tonearm on a VPI Mk.IV.

The majority of fine tuning I have done was with the VTA and tracking weight (obviously one will affect the other). I believe the Grado is a slightly taller cartridge than the BPS.

Best of luck with your new rig.
