Gary, That sounds like what I am hearing, thought it was a relay controlling the fan, but as you said, it did not pop when the fan came on/off.
Joe N9VX ------------------------------------------------------------------------------------------------------------- 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 On Thu, Dec 8, 2011 at 12:37 PM, Joe Word <joe.n...@gmail.com> wrote: > My KPA500 has developed a heat expansion pop.
