You can do an internet search for the "pin out" configuration of your DIN, then buy a super cheap RCA-RCA interconnect from Radio Shack and cut the RCA connectors off one end.
TIn these ends with solder (or if necessary) solder some fine solid copper wires to serve as pins and plug them into the DIN.
The DIN is four connectors plus ground. The four wires in the RCA pair are four connectors without ground. Don't worry about the spare ground for the break in process. Obvously, the pins on the RCA are left and right + and left and right -. (Same as your DIN).
Plug your original phono/DIN cable into a high level RCA input on your preamp and plug the Radio Shack RCA end into the output of your CD player.
Put in any disc you please in the CD player and play with repeat on. A CD player is about 1 volt output, much higher than a phono cartridge and the bandwidth of the music on the CD is sufficient to speed up the break in process.
In my own system I do exactly as I am suggesting you do, I even have a pair of RCA to XLR burn in wires made from Radio Shack cables.
