Steve,
I was looking for insight. For instance, is there a power up sequence for
the +5 & +12V? Anything I can look at before I dive in to the can?
This is not the first HP oscillator I have that has gone dead on me. I have
a 10811 that went south on me a few years back. This is just getting
expensive to replace them when they go bad.
And yes, if there is someone out there that can do it, I would consider
sending it out for repair. I'm an electrical engineer, but I also know my
limitations, and although it would grate at me to send it out for repair, it
would be the right thing to do (if the price is right)

Well, if your not prepared to open it up to fix it yourself, are you
looking for someone else to fix it for you (your postings need
clarifying)?
