[ETO_Alpha] 91B Load Settings on 160M

[Dennis Ashworth]

My 91B loading capacitor setting for maximum output on 160M occurs at 
a setting of zero, which I suspect is maximum capacitance. At this 
point, there is more grid current than I would expect to see so I 
must reduce to drive to prevent excessive grid current levels. 
Maximum power output is around 800W at reduced exciter drive. The 
load control setting at zero correlates with the final QC checklist 
which accompanied the amplifier from Alpha. Measurement are into a 50 
ohm dummy load.

Model 91B S/N983110748 shipped 12/08/98

I suspect additional capacitance is required to properly load the 
amplifier. Is this a reasonable assumption? Anyone else experience this issue?

Many thanks
