The only true way to know your capacitance is to measure it using a meter. Many turntables have well over 150pf of capacitance in the captive tonearm cables alone, with some vintage decks having almost 300pf or more. That's too much for many AT carts, before you even get to the preamp capacitance. Some folks also like to tune down the resistive loading to 32-39K to flatten excess treble response. If you want to tune it as flat as possible you'll need to make some loading plugs and use it in conjunction with a test LP and some software. Many of the AT YouTube videos are not showing these carts in a good light at all because of improper loading. It's like playing a CD rip from a CD with preemph, then not decoding it properly.
