[Elecraft] K-2 is toasted (I think)

[Don Wilhelm]

Rick,

First thing is to verify the 12 volt DC input path.  Look at the schematic
for the RF Board sheet 1 and you will see the components in the lower right
corner that show the path for the input voltage.  Check for voltage (should
be almost equal to your power supply voltage) at each end of each of these
components.  If you find a voltage close to your power supply output voltage
at all points, then at least you have voltage coming into the K2 from your
power supply.

If the voltages are a lot lower than your power supply, there is a break or
a short somewhere.

Let us know what you find with the initial steps above and depending on the
results we can decide what the next steps are.
