There’s a power adjustment write up . Google it . Don’t remember where it’s
at. I had a intermediate pot . Replace it and when through procedure. My
most stable power output was about 90watts on 40 meters . If you go past
wanted power output have to back them off and start over! Not the best setup
but it is the way it is. Hihi
Important to do adjustments as in write up!

Hi,
Hope someone has experience how to align / adjust the two potentiometers
within the pa? I found the pa is unstable and power output fluctuating and
expect the potentiometer or any component surrounding the bias might be
defective.
Hope someone can share experience.
Regards and thanks Onno pa1ap
