[Elecraft] KPA-500 Running hot on 20m

[W0MU Mike Fatchett]

I was running the RTTY contest this weekend and expected to see higher 
than normal temps but on 20m and maybe 15 the amp was running 65c and up 
where the highest speed fan would come on. Generally in RTTY I would up 
the normal fan a couple of notches and it would be fine.   I was not 
pushing it for full output either as I was not serious in the test.

Nothing much has really changed here so I am a bit confused what might 
be going on here.
