Re: Telequipment D75 scope.
Sorry about that Denis. I did not know that the knob was loose on it's collar. I am more than happy to give a you a full refund on the cost. Perhaps a little epoxy adhesive will sort the problem.
I have owned 3 scopes that used the S2A module. On every one of them the timebase knob is much stiffer to operate than the V/div control. I think that the extra stiffness is due to the timebase switch having more wafers.
