Re: 465B shielded transformer?


I am guessing given the compactness of the scope that this is to prevent 50-60 cycle buzz to be shielded from the rest of the internals of the scope not to shield from the outside world.

Hey y'all,

After the talk about grounding and X caps, etc, I figured I'd take a look at the 465B power supply schematic. To my surprise, it's a linear supply, no switching there and hence no noise suppression X/Y caps.
What really caught my eye is that the mains transformer also looks to be shielded. Is this commonplace in scopes of the era?
