I have the same turntable, the Denon DP45F. The date code (on the rear) on mine is 1980.
You can use any good to VERY good high compliance cartridge, as long as the vertical distance between the stylus tip and top of cartridge is not too great. I say that, because there is no adjusting the height of the tonearm.
That Denon uses a very light weight tonearm, relatively, to other TTs out there. The Servotracer arm solves many problems that other TTs have, namely tonearm resonance that depends on cartridge compliance/tonearm weight, and tracking of warped records by having the servo control "bounce" that other arms just can't handle.
Once you have used quite a few cartridges on your Denon as I have, you will learn that you have been spoiled by the tremendous tracking ability of the Denon ServoTracer arm. It does amazing things with warped and scratched records! Where some cartridges sound great, they don't always track that well. They will readily jump from scratches and warps on most other turn tables. In short....choose a good cartridge, the Servotracer arm will keep the stylus in the groove for you, and solve the arm resonance issues in a very wide range of cartridge compliance ratings.
