[Elecraft] K2 won't come on.

What may havew happened is your finals have failed. Try removing T3. This will remove 12V from the finals. Try to see if it will then power up. If so you have found your answer. Order a new set.

HI EVERYONE
  My K2 has been working great for over a year. turned it on this evening
and the light flashed and the internal fuse blew. I removed all the
options(100watt,noise blanker and ssb board). hooked a meter to the ground
and 12v input and have 12v with the k2 on or off. U4 and u5 (regulated power
supplies on the control board) Nothing. I might have to send it to Elecraft
but any ideas would be great.
