[Elecraft] KPA1500 Odd Happening

[Bob McGraw K4TAX]

Sounds like a power glitch.  I’ve seen that with my KPA500.   My amp is powered from a 240v line w/neutral.  As to why unplugging was necessary, I can only speculate primary leakage current or line input filter, which is in the microamp range, was a contributing factor.

I tried turning off the Amp and the Power supply several times to no avail. Finally I just unplugged the power supply for a few minutes. Plugged it back in and fired the ps and amp back up and all was normal. WHEW.. glad for that but.. WHY did it do this?
