Hey, I just aquired a Nicolet Instrument Corporation 2090-IIIA dual trace O-scope.
I have one line on the screen but I cant get the inputs to show anything. they apear to be able to switch between functions good and I think I have found the right output line comming from them. I get varring voltage at this line when I feed a low frequency sine wave to the inputs.
But that signal is not getting to the display.

Any sugestions ot ideas? Does any one have any experiance repairing these units? Or even a good schematic? I cant find much usefull info online.
Just that they say these were good units and are still worth alot when they work!
