up to 1 GHz.  No working Spec An on my bench now, but I have access to one
if needed...

Jim what kind of test equipment do you have? Kind of helps to understand
what approaches could be used to figure it out.
Funny I have a HP5061 CS its a true Frankenstein in reality using a 5060
tube. Absolutely on its last fumes. I have had a funny offset forever in it
and finally figuring what the issue really seems to be.
Crazy stuff.
