Arv,
This is how I've always operated my linear amplifiers. Tune for max in
CW and then mark that level on the oscilloscope. When in SSB never go
above that level with your modulation. It's a pretty conservative way
to operate but it's also the easiest. You don't have to worry about
trying to read a trapezoid display for linearity!

As long as the microphone port audio input is below 45

to be down at least 50db, but can be pushed even further down by
reducing the audio
level to around 32 millivolts. This seems to be where oscilloscope
peak-to-peak RF level
is about the same as when using CW mode.
