I've had this really nice old Grundig reel-to-reel kicking around for a while but it's been pretty much useless as it has these din type plugs on the back instead of our new fangled 1/4"s.
I've never seen a 4-pin plug like the ones on the left and I've never seen a 5-pin din plug that has "swept" plug-holes instead of straight ones, if that makes sense. Also to add to the confusion I have absolutely no idea what those symbols underneath the plugs mean.
So I'm going to buy a couple of 5-pin din to RCA cables but I'm wondering if they'll fit in that weird plug-hole?
Any hints on what the rest of it means/does?
