I can¡¯t say that I see a pot mounting nut on my old 453 unit. Where should I
look?
Remove the aluminum cover sideplate, mounted with two nuts accepting Allen screws (Astig and Trace Rotation) and the variable time/div knob.
Underneath, you'll find the nut holding the pot. It's mounted on a recessed part in the extrusion.
