Modern Cartridge and Stylus for Rheem Califone turntables.

I have here a mid 60's Rheem Califone Director -ll Model 15V tube turntable/PA amplifier. It's a hardy piece in excellent working order. The needle needs to be replaced. Instead, I was thinking of an upgrade to maybe an Ortofon, Audio Technica, Sumiko etc. If anyone knows about this stuff, please help me. I'd be very grateful. 20220811_194838.jpg
 
That's almost certainly a ceramic cartridge and a 8-gram tonearm. It will at least need a "magnetic preamp" and a re-jiggering of the arm spring.

Then every Rheem I ever met rumbled like a large old farm tractor, or like Bayside Road when the frost is coming out of the pavement in Spring.
