Colour Coded Diode

We're getting way offtopic here, but you do realize that 110 -130Vdc was fairly common voltage in all things with CRT's?

Yes. I have worked on a monitor or two.

85Vdc is not even close.

Sorry. Not knowing your degree of electronics knowledge, I (wrongly) thought that your question suggested that you were starting to illogically go down the path of, "The zener must be low voltage (relative speaking), because I've never seen large voltage zener diodes in use." I have seen some illogical logic on these forums.

So, an 85V zener. Specialist military equipment cannot be ruled out.

When I was young, I used to watch a science education program on TV, one hosted by a Dr. Julius Sumner Miller. I seem to recall that when some poor primary school student used the word "assume", Dr. Miller would chalk up "ASS U ME" on the blackboard, whilst saying something like, "Assume makes an ass out of you and me."
 
Actually in Mathematics its fairly common to start with "Assume" and then go on to show either the assumption is wrong.....
... my repair man says he thinks it could be an 85V diode or a 1N85 as the code were sometimes used like that, but a I don't think the part number matches the description.

Chris, he did say the ceramic tubular caps next to it were often sources of failures, and he would up end the diode and test it on a curve tracer....
