The Shure SC 35 cartridge can take quite a bit of weight and is excellent for
playing warped discs, but only with the SS78E stylus, not the pathetic little
N78S they brought out as its "replacement". For years I used a Grey Research
Arm with a flat-top head, which was great for adding coins and not having them
bounce off. For extreme cases, a Dominican Republic half dollar worked wonders.
