The 47 ohm wire-wound resistor that feeds the 10uf @ 350v cap was open. Replaced and now have 252vdc at the 251v source. Found the brightness control on the luminance board. The front picture control seems to be a sort of fine brightness control rather than contrast. Have things sort of dialed back in, at least it's a start. CRT appears to be healthy, and I found the original label that had fallen behind the fold down chassis.

Thank you gentlemen for your help in identifying the fault.
