Hello New,
Not sure what your question is-- where are the "RCA jacks" ? On the tuner, and/or on the turntable?
Gotta be more specific, as we can not see what you are doing--unless you post photos---

The original phono uses two "pin" type plugs, or three if stereo.
Also, the phono uses a ceramic cartridge with .5 volt output.

The OP's questions are too vague to determine the problem.
The Internet is a marvelous thing, however it's not a good substitute for actually being there.

From a picture search it looks like the typical 3-pin DIN plug is used for inputs:

Or you can get a pre-made male DIN to RCA cable.

Those old German receivers used a higher level radio demodulation which fed as much as 2 volts to the volume control. The original pickups used were high output crystal or ceramic. A modern and better quality ceramic will have lower level and you'll have to turn the volume up when playing records.

A better alternative if you are replacing the original turntable is to use a magnetic cart with higher output such as the Stanton 400.v3 which may still be available and/or a preamp with higher output on the order of at least 1 volt for a 5millivolt input.
