[Elecraft] KPA100 and Audio Issue

[Bob McGraw K4TAX]

From my experience Don is correct that a failure of the KPA3A will cause distortion.  Mine failed twice and was replaced by Elecraft. 

The best description of the failure is “fuzzy audio”.   I don’t recall the output was showing less than 100 watts.
