[Elecraft] dead transistors at the K2

[OE5CSP-Chris]

Hi,
I am using here an K2, serialnumber about 3000 and more. Yesterday i tried
to tune. The effect was: no power output at each qrg. Than i solder out the
Transmittransistors 2SC1969 and checked with an ohmmeter the routes Base -
Collector, Base - Emitter and Emitter - Collector. In one way Emitter -
Collector i measured at each transistor an resistor about 30 ohms. 
Now i do the same with drivertransistor 2SC2166 and i got the same effect.
They all died! Now i checked the predrivertransistor. oh well, he is living.
But i dont know, how i killed the transistors. the cause or reason ist
unknown. 
Then i bought in the local elektronikshop for little money new transistors
with the logo from mitsubishi. Then i called via phone the elecraft
distributor in germany and he told me, that most of these transistors are
fakes.
That is the situation.

Lieber Manfred!

Du brauchst die original Transistoren von Elekraft.Hatte das selbe Problem
wie Du!! Europäische Mitsubishi Transistoren funktionieren leider nicht!?
