I am currently working up a RM564B ?- seems to work OK except the fan doesn’t go round.
It’s not jammed, it spins freely by hand, and ?the blades are not hitting anything (there is no guard or dust filter ).
Before I tear into it, does it only run if the instrument overheats ? ?No manual that I can find – TekWiki has it on their Wanted List.
Many thanks
Tim
