Keep in mind that those needle drops may leave a click in the record (even when the stylus/cantilever is fine, that's a risk, unless you are dead-eye on the space between tracks). Thom/Galibier explained the issue very clearly in terms of the skew of the motor assembly; his point re the condition of the stylus itself is a good one. The angled cantilever is a little like having a misaligned drive shaft between your motor and the differential/wheels. If it isn't straight on, when running the road (grooves) it isn't going to behave smoothly. And could result in mistracking and explain why you lost signal in one channel.
It's all good to experiment and have fun but I'd be cautious about damaging your records. I also don't know anything about the quality of replacement stylus assemblies, such as those sold by 3d parties. @chakster would be your man among others on that question. Good luck!
