I'm quite surprised you have such an interest in the 500-E MKII. The original design dates back to the early 60's, and is essentially a cheap, 2-coil design that was remarkable over 40 years ago, but by today's standards, is really a poor performer. It, and the equivalent Pickering V/15 series cartridges were easily eclipsed by the Stanton 681 and PIckering XV/15, 4-coil models, which were introduced around 1967. No matter how the stylus tip was improved over the decades, with the "MK II" designations and the like, it's basically just a super-cheap cartridge and nothing more.

When Pickering and Stanton were manufacturing thousands of cartridges a month for "hi-fi" use, and not DJ use, careful attention to detail and super-terrific QC standards applied. You can bet your bottom dollar that such an approach isn't done today, as it's just too time consuming and costly. The company rightfully manufactures mostly DJ cartridges, and the handful of consumer, or "hi-fi" models that occasionally roll off an assembly line don't get the tender, loving care their predecessors did. I'd suggest you try something else.
