[Elecraft] K3 Burn In

[Brett Howard]

Has anyone done a burn in on their radios to test?  They rate to 100W
100% duty cycle for 10 minutes.  I'm sure there is quite a bit of
headroom in that too.  Has anyone tested to that?  Do any of the
Elecraft guys object to that type of testing?  

I had a strange failure at FD this year and worry that unless I do a
burn in like that once it gets back that my normal amount of operation
will take quite a while to emulate what the rig saw during field day.  

I'm assuming that the PA won't let you go till things are too hot and it
will protect if things get a little too hot under the collar.  Is there
any sort of permanent damage that can occur by doing this type of
testing?  I just want to be sure that I end up with a radio that I can
spend some time with and get ALL the options into over time.  

Other than my K1 this will be the first HF rig I've personally owned.
I'd really like it to last me a long time.  During the week I owned it I
REALLY loved the thing!  Now going back to the K1 I really miss the
K3! :)  Don't get me wrong I LOVE my K1 but its no K3! :)

If there are any tests I should do other than trying to measure MDS with
my XG2 and trying to do some key down tests to try and prove out that I
have no issues please let me know.
