Weird HP-71B behavior...

[KF6GPE]

Thanks, Bob! I will do that, and let it sit for the week. It's not anything I desperately need to fix, and I have a hunch the less I take apart, the better off I am. I have an increasingly poor do-it-yourself track record.

That's interesting, because what you describe (other than the sounds) is exactly what I'm seeing. Good to know.
