A lot of the original Philco "dynamic" cartridges were ruined by people trying to insert a steel needle where only a special stylus was designed to fit. The steel needle, having a larger shank than the original stylus, ruined the cone the stylus fit in.
I suppose one could install a magnetic cartridge in place of the "Dynamic" with a 78 rpm stylus. Unless I'm badly mistaken, the Philco "Dynamic" cartridge is actually a magnetic cartridge. I've noticed the sets that used it had a built-in phono preamp, using a triode tube or one-half of a dual triode.
The 47-1230's original changer uses this "Dynamic" cartridge.
You could really "hot-rod" your 47-1230 with a Grado 78E.
You might have some issues with tracking weight, though. I see the Grado 78C and 78E both track at 2 to 5 grams, so maybe weight would not be an issue after all.
