AT33PTG/II upgrade? Compatible?

Its a great choice - the AT33PTG/II is a great cartridge - I actually prefer it to the more expensive OC9 series.

Compliance is not low - it is a little bit below medium - so should be fine on your TT.

Gain & Loading are very configurable on your Sutherland via internal DIP switches and from what I can see you should be able to configure it for the AT. They recommend 100ohms minimum, but you can experiment above this and use your own ear.

Best of luck, I've got a Nagaoka - the AT33 will be a significant upgrade.

It is a very smooth cartridge in terms of sound balance.

Adding to what @dover said, its performance will also depend somewhat on your MC phono stage or SUT.

The resonant frequency with the AT and the Technics arm is about 9hz. That combination is fine!

@noromance and @dover  perfect thanks. Might pull the trigger this week. My first MC experience.

That’s what I got too @yogiboy  which seemed like a good fit.
