I agree the problem may be inside the rig, even though a "symptom" is 
voltage sag at the power supply.

But I disagree the problem is not a voltage swing, and disagree it would 
affect all bands equally.  My broken Jupiter experienced significant 
voltage sags on several bands, and produced 120 w on some bands, 60 w on 
other bands, and 100 w on still other bands.  Nor was it consistent on 
the same bands when I changed modes - one one band it put out 100 watts 
on CW, but not on SSB using a loud tone.  It would flip on other bands. 
  So it was not at all consistent and I could not discern any pattern.

Still, I agree the problem may be located inside the rig, and not inside 
the power supply.  Replacing the logic chip restored all bands to proper
