[Elecraft] K3 LPA failure, again

[Martin Sole]

Hi,

Might have been a bad choice of title!

Indications are the 7T transmit bias line is faulty somewhere. 7R is 
normal, 6.8-6.9 volts, but the transmit 7T line is very low, around 3.8 
volts. I suspect this is the cause of no power out anywhere as the 
signal switching is not working. The 7T line reads a mere 20 ohms to 
ground so I suspect a failure somewhere in what hangs from that line. I 
guess I will just have to work through it.

Maybe there are some known weak points someone might mention.
