I just received this beastie after purchasing it last week on the 'Bay, where it was listed as 'Doesn't power up... ...missing fuse...'. It arrived well packaged (actually double boxed), and while a bit rough isn't in terrible physical condition. I 'borrowed' a fuse holder cap from another piece of equipment, popped in a new fuse and after plugging in BOTH ends of the power cord (for my initial try only the instrument end was connected - d'oh!!
) it came at least partially to life, with the fan running, several indicators lighting up and a somewhat dim, not entirely focused display that's biased up from the center on the CRT and jittery in the vertical direction. The only key that seems to affect it is the beam finder, which gets the four traces more or less to mid screen with reduced horizontal width. It seems to completely ignore my poking and prodding at any of the other keys.
It displays a '25' on the numerical LED above the control knob; turning the knob causes no apparent change to anything. I'm presently scrolling through the PDF scan on the Keysight website in an attempt to get some troubleshooting hints and try to determine if the 25 has any significance as a failure indicator, and have also ordered a copy of the paper manual from everyone's favorite auction site.
I expect it'll likely need filter caps at the very least, but I'm pretty encouraged by the fact that it displays text and traces. If anyone who's worked on one of these wants to chime in with suggestions, all would be welcome.
