[Elecraft] k2 PA blown....

[Robert DROGOUL]

Hi, all Once again I have to come here to ask for help. The last thunderstorm took its toll, and I just changed the 2 x 2sc1969. The results are very disturbing !

On 40, 30, 20 and 17 m the signal look normal wheb in full power (10+ w), but as soon as I start reducing the power level and depending on band, the signal start to be mushy, finaly ending in burst of a few millisecond (seen on the scope). On 160and 80 m the bursts are present whatever power level is selected. Same on higher bands 15 to 10 m

I took photos of scope screen if it will help anybody able to help me solve this problem.

Thanks in advance, and reply direct if necessary!
