3.3.2 Tuning Control Settings
After alignment the settings of the tuning controls should approximate those shown in
Figure 3.2

3.3.3 Tuning For Best Efficiency
Retune CV32, CV51 and CV57 towards maximum capacitance to obtain minimum
supply current, but do not exceed a maximum drop of 0.5A per control.
Check that the supply current is:
T858 <12A for 50W output power
T859 <22A for 100W output power.
Note:
These control settings are normally very close to minimum supply current.
If the current is reduced too far, maximum power output will drop and 2f
rejection may degrade.
