[Elecraft] Dead above 40M - New Info

[K8RS]

Guys,
         After hooking up my antennas and running through the bands. I see
that the receive seems to work on 160M, 80M and 40M, but xmit is
questionable.  Most important, there is a message on the display that reads:
                  "51 nr .nt"
The manual indicates that a "51" is a general  problem with the control
circuits.
          Before I start disassembly, I would like to know if anyone
recognizes this display and can point me in the right direction.
          I have not begun to test the voltages, but have removed the KPA100
and am looking at the K2 by itself.  I have the KDSP2, KSB2, K160RX, and
KNB2 still installed.
