[F5UL]

Hello the list,

I posted,a few days ago an inquiry about a PA problem with my K2
Till now no return!
But I have a lot of changes since this post. The two PA Xstors finished with junction B/E open. 
After changing both of them with two new ones, the same reactions happend, that is very low output on 1.8, 3.5, 7.0, nothing on 10.1 and up.
Whenever I try to key  the Tx during some seconds, with power set at 2 watts, the curent start at 0.7 Amp for a few seconds, then go up to limit with High Cur indication. 
The power out goe down during this time !
I still had another pair of 2SC1969 to change, but the resultswhere the same...!!!
So I am lost. This K2 was working nicely and that incident happen suddunly just after turn on in the morning with a brutal howlin the speaker, and after turn of followed by turn on the apparition of this no fonctioning !
Who can help me pse?
