From the last mixer to the antenna CW and SSB are same.
I've seen at least two with a wrong 40M LPF, though it was TX power amp but 80 and 20
had higher power than 40.
Seems the coils had about half the number of turns, they were likely 10M coils and the
caps were also questionable for correct value.? Rewound and recaped it then produced
normal power.
So it can be simple but not obvious.
