Technics SL-1210MK2 - weird speed problem - Page 7

lcseh · 5th August 2011, 05:45 PM

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?

I have replaced by PCB board still the problem persists. recently the platter started to move super fast. only on hitting reset button the platter is back to normal.

Pls guide if any tips.

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.
