[Elecraft] KPA100 smelling....

[Karsten Eppert (DK4AS)]

Hi,

I?ve been using my KPA100 for a while and suddenly had a strange smell 
in my nose - like something being very hot from too many amperes. I 
opened the unit, could not find anything burnt or molten but found 
resistors R38/R39 in the final stage hot. I still could touch them 
without burning my fingers but they were the hottest components I could 
identify.

Has anybody an idea, how hot these R?s may go or whether they may heat 
up at all?
