[Johnson] Ranger Question

[Michael Hardie]

I'm still working on the Ranger 1, many problems have been solved but the 
output is still very low.  The buffer peaks and the final dips OK, and the 
drive can be adjusted to get 140 ma current in the CW mode. (No work has 
been done in AM yet)  There are two "oddities", the drive control is about 
1.5 on it's dial and the grid current reads 0.4 ma when the plate current 
reads 140 ma, the manual states that the grid current should be around 2.5 
ma.  And the 6146 screen voltage (Again with 140 ma plate current) is 160 
volts, not 190 volts as per the manual.  The coupling controls have very 
little effect, indicated power on an accurate wattmeter/dummy load is a 
couple of watts.

Ideas?
