Turntable adjustment


I've recently acquired a Technics SL-QD33 turntable with a p-mount cartridge. Anti-skate is factory set and non adjustable. Also, its fully automatic. Everything worked fine with the stock cartridge, but I wanted to upgrade so I purchased the Grado Prestige Green cartridge, which has improved the sound.  However, now when I start to play an album, the tone arm no longer places the stylus in the groove, thus, it slides off the record. What can be done to address this issue?

Am I reading this right? You put a $100 cartridge on a $70 turntable?

Anything around this level the turntable comes first. Live and learn.
Millercarbon, given the fact that the turntable didn't cost me a dime, the money I spent on the cartridge was well worth it.
The Technics SL-QD33 uses a P-MOUNT (T4P) cartridge.  So no adjustments at all, (other than the whopping .25 in VTF).  

I sold these back when they first came out.  Were meant to be a plug-n-play solution for the customer.  Too bad most of them sucked...

So a perverse example of the fallacy of the sunk cost. But an example nonetheless.
