Okay, I gave the DX-60 and amp as a straight forward example.
Again, I've never dealt with an AF-67 so have NO comment there! Won't
talk what I do NOT know!
I posed this as real world information. At no time did you say amp NOR
no amp. I'm not trying to stir pot! Just give KNOWN DATA POINTS.
You posted a couple of questions:

SSB with carrier, as the KWS-1 uses, *BEGINS* to bring in the earlier
issue of complete high, (plate level), level modulated systems.
Those are going to be more difficult to calculate as you only have one
sideband, and I do NOT know how much the modulator plays into power
calculations.
The values you present for the AF-67 give the appearance as being inside
the operating parameters of the SG-230.
