Until yesterday morning, I hadn't gotten past the VCO test.  It was
consistent with the following error messages:

E 00005
ERR VCO

E 00255
ERR VC4

I ran the test this morning with no error message, however instead of
clicking along at a very good clip, it began with the word "busy" and
then a slow count up to cal 127 and then to frequency readout normally.
  I can now hear traffic (net on 3.905 mc)!

Well then I got home this evening and found the K3 doa.  When I push the 
"Power" button, there's a bit of a draw on the power supply and I hear a 
relay clicking, but the front panel will not light and no functions are 
available. I tried going through the Theory in the manual and scoured 
the schemagics, but can't figure out the power distribution architecture.

This bums me out since I finally got the REF and SYN to play nice and I 
was getting into listening to ssb net traffic (and the ball game).

I have a call in to Aptos, but they're on the other coast and I think 
they probably went home (if they have any sense).  Does anyone on the 
list have any ideas?
