OK. I tried the aux input, but nothing. Then I realised P13 connector was loose. In fact there were several broken pins. So I changed the connector. I made no mistake, I'm sure. Anyway, black smoke appeared from underneath the alu panel. Result: IC2 LF 347 burnt. Before it wasn't powered at all, so it was impossible to predict! And of course

Yes Martin is right (is that a pleonasm? ). Beware of adjusting something while misaligning something else into the bargain! If you touch arm parallelism, it can influence the aperture setting too. When you pause/play the arm should lower and the carriage must not move at all. If it does, it is not properly aligned. This can be tricky to do and if you

You did the job! I was your eyes and hands! Is your replacement motor the same as this one? Mine is dated 1985 (but I've got another one, in better shape, dated 1981—it was on a NAD deck).
-
Couldn't wait! I replaced it (4TR9, BC547B) with a 2N3904 and it's a victory! Definitely a standard issue then. Martin, thanks for sharing your invaluable knowledge. So, you have belts and motors? On my deck, it's a smaller variation, the silver Matsushita one without the external transistor, curiously dated 1985 with reverse polarities
-
Okay, thanks! I will try to change it tomorrow. No PM though! But yes I'm interested in the belt and motor.
-
Ah well, thank you all the same Jeff! I've studied the auto-stop circuit and it works. Alas this doesn't affect the motor in any way.
-
Thanks. Yes this is strange. I can't figure out what stops the motor (its power supply) when it's put in standby. It's not very clear on the diagram (and I can read a diagram) and all voltages are nominal. Now there is indeed some optic device inside the mech but I don't know how this works. I tried my other mech's belts but it didn't

Anyone please? I'm becoming crazy!

[quote user="j0hnbarker"] The motor should start spinning as soon as it is out of standby, but should stop when the unit is switched to standby. [/quote] Thanks for the answer John. Yes I know (I have a Beocord 6000), but on this one the motor never stops! I was wondering whether this is down to the absence of belts or an electronic fault

Hello, I've just got a nice Beocord 8000. I want it back to life ! I removed the horrible belt rests (more akin to tar, really, yuck) that had spread everywhere and I now need new belts . I also changed the motor which was very noisy (I had the same Alps unit in stock!). The funny thing is it's actually smaller than the one on my Beocord 6000
