The main thing to remember with 78s is the groove size is different from 45s & 33s so requires a cartridge with a 78-sized stylus. While 78s will play with a regular cartridge needle, it tends to ride the bottom of the 78 groove and is far noisier than it should be.
Some modern cartridges with removable styli have a 78 needle available, so one cartridge can do double-duty if your turntable supports the 78 speed.
