Question about Technics SL-1200 Turntable
Technics sl-1200 major pitch control issues. Intermittently when turning on the unit both the 33 & 45 light come on & the platter spins @ mach 5. Im sure it's related to the On/Off control.
There seems to be 2 issues with this unit. Usually when the platter speeds up very quickly, one of the IC (integrated circuits) are faulty and needs to be replaced. However, I've never seen the 33/45 lights come on in addition. So, perhaps the issue started with faulty 33/45 switches, and it then caused a short to one of the IC's.
This will have to be professionally serviced, as it is not an easy fix. There are various circuits on the main board which control the drive, so it's a matter of diagnosing which is the culprit. The 33/45 switches will also need to be tested/replaced.
