Sad, but my good old MKII has also strange speed issue.
I powered it up after not using it for 3-4 months, and now it spins very fast, and the buttons have no effect on the spinning. By very fast I mean a speed of ~100 rpm.

Any advice, on what parts should I order, before I take it apart?

he guys i dont know if it makes sense. but i am actually planning to keep a piece of silicon on IC AN6675.

if the statement of overheating is true, this way it will absorb all the heat and keep the IC cool. not sure but i feel worth trying.... before buying stuff.

Default Problem solved replaced AN6680

Had the same erratic speed problem with a 1200mk2 from new. Never had it repaired under warranty as I was out living and working in the middle of nowhere. The problem in the early days would only start after the turntable was in operation for over thirty mins or the weather was hot. A nuff nuff at the $100 an hour dj city service in Melbourne told me it would almost definitely be the pitch slider - but after swapping pitch slider myself with working unit I confirmed this was not the issue. After reading on this forum that mnsh from Gothenburg and dgb from Auckland had fixed this issue by replacing IC201 I ordered one of these panasonic AN6680 chips through Amazon.com for something like $35USD delivered to Melbourne, if I recall properly. Now after replacing the chip and some rigorous testing, my turntable works perfectly for the first time in its life.

Default Same issue - Fixed!

I just wanted to add that I had the same issue with a 1200MK5 that I bought on eBay and thanks to this thread I was able to fix the issue! Replacing AN6680 truly did the trick and I've had worry free operation ever since! Thanks!
