Re: WTD: 7704A Power Supply

This is also partly due to poor focus in 7K CRT's in general since they use the
mesh screen technology . . . The typical "spot size" of a 7K CRT is several
times larger than that of a 453, 547, or 585A for example.

It seems the on screen readout, while a brilliant feature, is never quite
perfect. For instance, the character focus and/or astig never seems to be
quite sharp, and it varies depending on screen location in some models. Part
of the wonderful character of the scopes I suppose.
