[Elecraft] Why no power from SSB

[n0jrn]

OK folks:

After further checking,   I find that I have good power from SSB on 80, 40 & 
30 meters.

( I've taken the tuner out of the rig and have it hooked to a 50 ohm load 
with a watt meter in line )

What's got me pulling my hair is the rig is fine on CW on all bands.

I don't understand why it works on CW and not on SSB on the higher bands. 
I would obviously blame the SSB board and some mistake I might have made but 
there's nothing on the SSB board that is band specific
Is there ???

Still digging             :-)
