[Elecraft] K3 power switching.

[G4GNX]

Thanks Bruce.

I was expecting it to be on the sheet marked "Power Supply" and skipped past 
the RF boards. I have it now. :-)

It looks as if either the zener or the fuse or both have failed, so the rest 
of the K3 didn't get protected. What caused the initial failure may never be 
known. As for the smoke, all we can say is "it didn't oughta done that"!

This evening's club meeting may well reveal all.

73,

The 12V power in circuitry that Fred referred to is on sheet 3 of 4 or the
K3 RF board, lower right quadrant.
