Hi,
well, C3 and C4 on #2 board have been replaced but no change in the lifter issue.
i like to exclude the lifter/lower gear wheel as it performs basically the same task at the run-out groove of a record without any drama – no stuttering or rattling of anything!
same thing goes for the piston of the solenoid – leaves me with testing TR4/5.
As I see it : when the lifter function is activated a fluctuating power supply is fed to the solenoid……what else could it be ?!
