Re: lethality of HV
It all depends on the current. For an anode accerating system, there is
very little (or no) current, so the power supply only has small capacitors
in the voltage multiplier. There is maybe 10-20

Re: 7704a
Nice system. My every day 'scope is a 7704A with a selection of plug-ins

The timbases are older than the scope, but compatible.
The optimal timbaes are
7B80 (horizontal slot 2, main)
7B85 (horizontal slot 1, delaying)
The 7A18 are inferior to the 7A26, but

Re: 475A filter, protective cap availability?
Lighting gels are not very thin, because they are mounted in front of
lights, not lenses.
The dye is "cast" into the material.
