Rock-Ola 490 Turntable Motor Running

by Las Vegas Jukebox » Fri Feb 06, 2015 3:32 am

I have a Rock-Ola 490. Everything is working as it should, except for some reason the turntable motor is constantly running. I thought it was the triac in the power supply, but changing that didn't make any difference. Any thoughts?
Regards
Keith

Hi Keith,
Triac hasta-be controlled by something--switch/transistor ?? I do not have the schematic on that model--

Thanks Ron,
I will have another look. I have the manual and the schematic. I probably overlooked something. I am right in thinking that it is the triac which operates the turntable, aren't I ?
