[Elecraft] hello to all K2/100 owners, advise needed

[John Klokis]

I recently got my K2 serviced and updated.  I was told by the technician that I needed to tighten the mounting screws on Q1 and Q2 after 10 to 12 hours of use. Failure to do so could destroy the transitors. I have read the KPA/100 manual and it says to tighten these mounting screws after initial use.  My radio is 6 years old.  Do I still have to try and remove the board to tighten these mounting screws periodically when using high power(100 watts).  If so needed, can I access these mounting screws easily or do I have to remove the KPA100 PCB?
    My K2/100 and KAT100 really performs well since it was updated and correction of a problem fixed.  I do not work on radios, but I would try and do this maintanence if needed to prolong the life of the transitors.  John K3JK
