Re: Tektronix 465 No Trace, No Dot


I believe (someone please correct me if wrong) that you can simply
disconnect the deflection wires at the CRT, and of course that should give
you a blinding dot if you have HV, and if everything else is intact.

Also check for a filament glow. No idea if these tubes are prone to it but I
once had a scope with a blank screen because of an open filament.
