I failed to take into account the odd mounting of the original cartridge, which I was not thinking of at the time - the two screw holes are too far back. Johnny's photo clearly shows this.

Johnny, it looks like yours has an original stylus in there? The bad thing about those cartridges is that the vast majority of them were ruined by people removing the original stylus and forcing a steel needle into the cone, ruining the cartridge. The stylus just pushes into the hole in the cone. The hole is made just for the special Philco stylus; a steel needle has a larger diameter.

Once the cone is ruined in this fashion, the cartridge itself still has good continuity but it will no longer hold the proper stylus once the hole gets enlarged by a steel needle.

And Gib at West-Tech is not equipped to fix this issue. I asked him once when I had one that was ruined by a steel needle - no way to fix the damage.
