Hi

Does anybody know how to get the time/div clear plastic ring, the one
under the knob for the main timebase, off its shaft?

I don't want to damage the scope but after removing the delayed sweep
knob, the plastic ring with the time/div numbers is still attached to
the shaft and doesn't seem to slip off.

Has anyone ever removed one of these before? I presume its the same as
the 475 and 485's also.

TIA

I think there is a gear back in the module.

Go to Yahoo Groups' web site and look for TekScopes and TekScopes2 groups.
Join one or both.

LOTS of people there who can answer this (and future) questions to more than
your satisfaction.

Good luck!
