[Elecraft] KPA500 Heat Expansion Pop

[Dave Perry]

Yes, my KPA500  has been doing the same.  Whenever I mention it here on the 
reflector, I get zero response.  I cannot tell whether this is a problem or 
something that is normal.  The pops are very frequent regardless of mode. 
Otherwise, the amp appears to function normally.
