[Elecraft] KRC2ACC Problems continued

1.  I have quadruple-checked the polarity of every diode, electrolytic and
resistor pack.

2.  I have quadruple-checked the orientation of every ic and transistor or
voltage regulator.

3.  I have reheated every pin I could reach.

4.  I have not reversed X1 and X2.

5.  I have loaded the latest version of firmware, and it seemed to work
fine.  I used the correct version for the KRC2ACC.

I still do not seem to pass the initial checks.  I cannot get voltages to
appear on any of the "band relay" terminals.  Yes, I am checking at the
terminal itself, not the screw.

What is my next move?

Thanks for any and all suggestions.
