[Elecraft] Power Fluctuations on K2 just Built

[John Bahun]

I recently completed my K2 and I am noticing that my Power output is very flaky and does not seem to track the Power control knob very well.  I have tried both the TUNE button and the Key input with a Hand Key and I am getting power fluctuations with both.

I am suspecting something in the ALC circuit at this point - Anyone have any ideas on this - Since the installation of the two final transistors is kind of tricky - if they are not installed correctly - could this cause this behaviour?

Also - if I measure from the Collector of the Finals to ground - what should I measure in Ohms?  I would like to compare mine to someone else's K2 to see if I might have a partial short in my finals.

However - the way the power fluctuates - I am really suspecting something in the ALC circuit - Just wondering if anyone else has run into this issue...

Thanks in advance!
