med6753:
The only HP scope I've used is the 180A. They were used  in IBM mainframe test in the mid 1970's before going to Tek 475's. I found the HP to be easy to use and decent but a lot of other techs thought they were junk

It has some very nice touches internally and some crap ones as well. The rotary switches are both a clever design and bad at the same time, clever but poorly executed as they wobble all over the place when operated putting flexing action onto the boards that they plug into.

Worst feature: abrading the PCB track as they are rotated.

Second worst feature: when reassembling, getting both the timebase knobs in the right position simultaneously.

and how about the lubricant that turned green and hard as a rock at about the 25 year mark?

Yes I would think abrading the tracks is a problem a scope that has been used a lot, thankfully, thats not mine, it is almost as good as new inside and you spot on with the timebase knobs/shafts they are a real pain  in the arse.

maybe its an inherited trait.

in 1968 my old man was 'bout the only guy in the greater philly area to buy a racing green import called a "cortina".  what a piece of dog shit it was.  every morning before cranking it over he had to look underneath to see what had spontaneously fallen off it overnight.  the ford dealer never could make it right and finally took it back (he got a torino to replace the little green turd).

to this day he loves that damn cortina.

and I love my 1740 series scopes.
