[Johnson] Ranger Help

I'm trying to restore/get running a Ranger 1.  The current problem is very 
low output CW and AM all bands, with the plate dipped there's between 10 and 
15 watts.  If the final tuning control is turned away from the dip, and the 
plate current kept below 140 ma by reducing drive, 50 watts ouput can be 
obtained.  The coupling controls don't have much effect.

Changing the 6146 or the 6AQ5 didn't affect anything.  The screen voltage on 
the 6146 is much higher (380 volts) than the manual value. (190 volts). 
Other voltages are in the ballpark and I think I've found and corrected all 
the wiring errors.

Any ideas on what to do next would be appreciated.
