I have a Tektronixs 422 scope that I've had for years. I'm getting ready to
put it up on eBay - but is has a "whine" when it's on. The traces are fine,
everything works - but I want to be honest and not have any buyer trouble.

Is this normal in an older scope? What is it, can it be fixed? It's a
really nice older "vintage" scope - just never use it and need to find a
good home for it.

please email me at since my newsreader service
never seems to keep any old messeges.
