Mine pops or clicks too. In my case, it sounds like a relay switching. I thought at first it was something sensing the temperature and changing the fan speed, but the pop doesn't (often) coincide with a change in fan speed, so I think that's a red herring.
Another ZL told me his KPA does the same thing. Our amps still work just fine though! 73 Gary ZL2iFB > -----Original Message----- > From: [email protected] [mailto:elecraft- > [email protected]] On Behalf Of Joe Word > Sent: Friday, 9 December 2011 6:38 a.m. > To: [email protected] > Subject: [Elecraft] KPA500 Heat Expansion Pop > > My KPA500 has developed a heat expansion pop.
