[Elecraft] K2 no audio output on Part I Test

[Don Wilhelm]

Mario,

No, 5 volts there is not good at all.  You should have zero volts DC, 
but there may be some AC riding on that level.  What is the voltage at 
CB U9 pin 6?

I am thinking that either you have a solder bridge or you have a shorted 
C29.

73,
