Re: Philips N4450
The latest on this machine. I found my old Philips headphones with the 5 pin 360 degree plug which are historically the right ones for this machine. I wired a couple of cheap microphones to 5 pin DIN plugs (why is there no standardisation as to the pinout of these, Philips and B&O use pin 1 for the signal, Uher uses pin 3...) and plugged everything it.
It works fine. I can record, play back, monitor off-tape etc. Never having used a machine with separate record and playback heads for microphone recording before, the delay between speaking and hearing the off-tape signal in the headphones took a bit of getting used to.
So I've put the covers back on. All that needs to be done to complete it is to make a trim strip for the plastic dust cover (I mentioned that many posts ago).
