[Elecraft] Need help for sick K1

[Rick Dettinger]

When I built my (second) K1-4 last year, it worked fine in all respects, with output as expected.  Couple months ago it turned into a K1-2.  I got full power on 40 and 30 M but less than 1/2 W on 20 and 15 M.  I took it apart and measured RF voltages on 20 M.  They were low at all points.  I put it together without the tuner.  It worked on all bands.  A K1-4 again.  I put tuner back and it still worked fine.  I used it without problem until today.  Bact to a K1-2 again.  20 and 15 M had less than 1/2 W.  I took it apart and removed tuner again.  Big change.  Now I get too much power on all bands.  10 W on 40 M to 5 W on 15 M.  I have never got more than 7 W on any band.  I turned power down to 0.1 W and still got high power on all bands.  Also, the RF indicator on the K1 dosn't work.  No bars light.  Looks like I have a power control problem.  Like no control.  Any ideas?  Supply voltage was 12.7 V.
