It's a 1960's scope. I recapped the PSU, but have to recheck them now with a LCR meter. It had a funny regulation 'problem' too, but it could be fine for ll I know. And I never fully load tested it yet, I'll do that soon. I want to recap the scope 1/2 and see what happens. I put it off for too long, and I'm really looking forward to it, with new tools. and on a new workbench.

What quality of elec. caps are really needed for this ? I have some cheap ebay ones and not much else, I did choose their ratings with this scope in mind.
Some of the caps are in sturdy metal tubes, perhaps for shielding and for physical protection. But there are labels on the tubes, so it could be the actual cap is jacketed ? I'll check tonight.
They are all listed in the great Tek422 manual, what key elec. caps should I order brand name caps for, like in the HV section ?
Is there anything in the HV section I should be be worried about. IDK how this one works, is there any potted stuff like voltage multipler's that should be checked somehow ?
