Whether a RTTY signal is generated by actually shifting the frequency of 
an oscillator or by driving an SSB transmitter with a single tone that 
changes frequency, the result is the same: a continuous signal whose 
frequency shifts between two values.

In other words there's no difference between FSK and what people call 
AFSK except the means used to generate it; and it can be amplified with 
a class-C amplifier if you wish!
