Re: Update on 2465
thanks for the correction - can you share where you come by this
Naively I looked at the HV and CRT circuits, and took the -900V line from
the HV supply towards the front of the CRT neck to go to an expansion mesh.
Hmmm, maybe just a case of RTFM :). The -900 is termed "slot lens voltage"
in the Cathode Supply section of the Theory of Operation.
Incidentally find that there's no contest between the spot size and trace
clarity between my 2465 and my 485, the 485 has a much clearer trace. At
one point I routed the X/Y/Z from my HP8566B's display unit to a scope for
diagnostics of the display unit, and the 485 was the only scope I own that
was able to resolve the detail. See <https://goo.gl/photos/21ASGFDsU2Zd9qA66>
I believe that display is 1024x1024.
Maybe this is just a sign that my 2465 needs some TLC, though after I got
the 2467 she'd be better with someone who'd use her more, probably :).
The dot size on my 2467 is quite absurd in comparison to either of those -
though it wins hands down on brightness (which is the MCP trade-off).
