Thank you for your reply, Dennis. Unless this is radically different from the
468 re initial control settings, I cant get ANYTHING to appear on the
screen..... I think the CRT is not "lighting up". There is no filament glow
in the tube (observed through the slot in the tubes metal shield), and the
beam finder does nothing. Compared to the 468 the CRT seems to be "off or out
of the circuit" ie not getting filament voltage and or HV.
I looked more into the fan control and it appears to be temp controlled, so
off when the unit is first turned on? Even with the power on switch "on" and
the indicator light showing power on, the fan still never comes on for say 30
min. I have not tested it longer than that.
In the download of the manual, i didnt find FIRST TIME USE, but it seemed
pretty similar to my 468 and other Tek operational tutorials.

Start with checking the LV test points. Of course after you are sure you have the controls set up correctly. HV relies on the LV being correct.
