What kind of magnetic cartridge?
Hello. I did find on ebay for sale this "Grundig" tube radio: https://www.ebay.com/itm/20344697380...0AAOSwMCxgmDJb
On one of the pictures a 5 pin D.I.N. conncetor PU (magnetic) appears. PU means pick-up, so cartrdige or record player. But there where any magnetic cartridges in the late '50's - '60's or it was for the old electromagnetical cartidges? (horse shoe magnet). |

I don't really know, but since this device is stereo, I don't think it would accept the old cartridge.

If I remember correctly, stereo records became mainstream in 1958.
“1958: Shure introduces the M3D stereo Dynetic Cartridge. It is the world's first moving magnet stereo cartridge and features stereo channel separation at 1,000 Hz of 20 dB or better.” from: https://service.shure.com/s/article/...language=en_US jr |

This being a US model; Input DIN labeled Mono PU & (crystal) suggest an input matched to higher level output of older crystal cartridges.
PU probably means pickup used interchangeably with phono. The stereo "TR" likely means tape recorder, equipment sold as stereo before there were stereo records. This input would likely be a line-level and able to be used with a ceramic stereo phonograph cartridge. Using DIN-to-RCA patch cord makes the connection easily.
