Default Re: Confusion over DIN sockets

Because the Grundig is a mono recorder, Pin 1 must be joined to pin 4, and pin 3 to pin 5 in the 5-pin DIN plug at the end plugged into the Delta 30, or, if the amplifier is opened, the pins can be joined as above on the DIN Socket. The only drawback to this is that, although this mod. is reversible, unless this is done, if, in the future a stereo tape recorder is used, any recordings made will only be mono.
A.F.A.I.K. No harm will result to the amplifier by bridging the channels at the DIN socket as described, but perhaps other members would like to advise of any possible snags involved (I don't have a Delta 3o circuit diagram to hand)
