Matching stepup to phono stage

Keep the CJ loading at 47K.

You need to choose the right step-up transformer to present the recommended loading of the cartridge AND simultaneously give you the correct amount of gain. The impedance presented to your cartridge will be the combination of the 250 ohms of the step-up and the 47Kohms of your phono stage.

Adding resistive loading to inductive loads, pace Bent Audio, is not recommended.

Sorry, I didn't mean to talk down Bent Audio - John Chapman is a great guy who makes fantastic products. I just don't agree that it works to add resistors to step-ups to gain the desired load - from my experience with 8 or 9 different step-ups in various configurations with different carts and phonostages, it's always more desirable soundwise to get the load right by choosing the right step-up.

For a general discussion of loading, with formulae and online calculators, see Hagerman's page on the subject:

(Note: Hagerman also recommends varying the load with a resistor at the phonostage side - I've only done this once with a step-up, back when I had a Rogue 99, so I have less experience than with adding a resistor before the step-up. I'd still guess it's advantageous to simply choose the right step-up for your specific cartridge - keep it simple.)
