[Elecraft] KPA1500 RELIABILITY

[john at kk9a.com]

Is there a common component failure with this KPA1500 amp or does something
different break every time?  Is there a certain mode, power level or type of
antenna/feedline that causes failures?  I also monitor the SPE Expert list
and some people have multiple LDMOS failures while others have no issues
ever. N4ZR posted a similar question two months ago when someone else had
multiple LDMOS failures and I did not see any responses.

I don't have one but I do have access to one. It is making UPS rich 
going back and forth. Is there a reliability issue with these amps?
