But if you start with mono, it is sequential; 1-2-3. Add in stereo: we'll insert 4 and 5 in between. 1-4-2-5-3. So the additional pins still number clockwise. (QUAD ignored this for a while) Now someone wants remote control (like Grundig did) so we'll put those below the audio pins; 6-1-4-2-5-3-7. You can tell I wired a lot of DIN plugs up as a kid! The less said about pin 8 and its physical position the better.... |

When I was at primary school it was a different matter: then Clarke and Smith dominated but tape recorders were lovely Truvox R102s - 3 motor, 3 head, 3 speed machines. I have one |

Re: Grundig TK30/35 remote control
Interesting to hear that Tandberg was dominant in schools also outside Scandinavia. They were certainly dominant in Sweden where I grew up, but part of that explanation could be that Norway is a neighboring country.

At least on the older Tandbergs, if you pressed the backspacing pedal while recording, the machine would rewind while in record mode, erasing what you'd just recorded. I don't know if they built some form of backspace record inhibit function into the later machines. |

There was I think a modification bulletin for the erasure-backspace problem. The series 15 SL was actually a standalone student recorder not (initially) meant for use with a teacher console. The track selector would enable you to record on either upper or lower track, then by setting it to 'student' you would enable playback of the master and simultaneous recording on student track via the mic. I expect most of these were used with pre-recorded copies of lesson tapes. The 10-21 was the one meant for language lab booths in conjunction with a console. It had solenoid pause (a backspace/footswitch version may have been available, will check the service manual) and unlike the 15SL, recording on the lower track was only enabled from the console by supplying power to the oscillator. Well, apologies for drifting off topic, if there's any more interest in Tandberg LL kit we might be best off starting a separate thread.

Also see that the 4 pin DINs pin numbering is sequential, so my assumption that the SL remote connector was a Tuchel was incorrect. David |
