phase linear 400

Gene, do you know there are other Forums on this site? Testing, Speaker Building, lots of Discussion Groups.
You are not required to post everything on the Amps, PreAmps, and Receivers thread. We don't mind, of course. But you might attract a Fluke expert in the Testing Forum, for example. You have such talents and insights, it would be good to share them in some other threads.
For anything related to the PL400, this is certainly the right place.

Suggest a DER EE DE-5000 LCR meter for caps. What model of 77 do you have?
The 8050A does diode checks. Actually has 3 separate ranges for "turning on" silicon junctions.
Huge operators manual.

Not I Gene. All the components I use are senior friendly ?-)
 
Here you go Gene. Corroded traces on the board. Perhaps caused by flux residue. In the article that's linked, click on the additional link for the 77 IV. Good comments all through the links. Need to open up mine and look for the white residue. None was on the 8050A, need to check the two 77/BNs. Didn't know Fluke has these issues. Disappointment.

Some have even found corroded vias. I see yours is also a BN, produced for government contract. May have had a hard life.
