Re: display tilt adjustment hp8591a
You do not per chance have a steel workbench or similar? As I have found out the hard way ages ago (i.e. during my education) such an environment can affect tube trace alignment.

I suspect that's likely a magnetically deflected display, like a television, and has a deflection yoke on the CRT neck that's somehow managed to get rotated slightly.

display tilt adjustment hp8591a
Hi,
I repaired an 8591A for a friend, but the display on his screen isn't
perfectly straight.
I'm guessing there's an adjustment for that, but where is that adjustment?

I think it is likely to work - BUT, the assembly and disassembly will be (at lest) challenging.
The thermistors may be similar, and possibly the thermistor board in the cartridge (you need to check

Re: OPT 003 (48-440 Hz compatible) fan (full size "Muffin" type fan) - replacement requirements?
If it is from a 8660, don't be tempted to go with a lower power fan, HP had some reliability problems with early 8660A & 8660B, this lead to them offering a free upgrade to a larger size fan in 1974

Re: OPT 003 (48-440 Hz compatible) fan (full size "Muffin" type fan) - replacement requirements?
The difference with the option 003 is that a *DC* fan is fitted rather than the mains (50/60 Hz) AC one in the standard unit. This give you more choice of replacment fan. Take the old one out and see
