After futzing around for a while, I finally figured out the relationship
between drive, rf output and alc. It seems like I need 2 settings for the
drive. One for 40m and lower and one for 20m and up, with a corresponding
adjustment of the rf output.
Now, the amp goes into an hard fault, indicating a problem with the HV
section, at random intervals. The transformer is tapped at 200 volts and
the line voltage runs from 210 to 225 volts.
Any ideas?
