I’m currently attempting to fix up a DUAL CS 505-1 turntable for a friend. It’s been sitting unused for 20 years and R1 on the switch-plate smokes after a few seconds when turned on. I’ve posted to a specialist forum on this (https://www.vinylengine.com/turntable_forum/viewtopic.php?f=18&t=124139&p=1119965#p1119965) and I’m making some progress but just thought I would run it by here in case anyone with experience/knowledge of these things is able to input.
Thanks!
