Nice! I'm surprised it has held that remagnetization that long!

Well, the fix was indeed to remagnetize the small magnets but, luckily, not every time I want to play a tape!

I removed the motor rotor so as to expose the three small sensing coils, then I briefly put a strong neodymium magnet close to the core of each of them.

That's all.

Ad I played many tapes since then. ;-)

Actually, I think it's close to 10 years now that it works flawlessly, but lately my backup hi-fi stack includes a CD player (vintage 1982) so I don't listen to so many cassettes these days...

I'm guessing he just remagnetizes every time he needs to play a tape?

So, what was the "no-brainer" fix?  

You said you could not replace the motor. and that the motor's magnets fail over time.  Shorting the coils does not seem like a fix, so much as periodic maintenence.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
