Yes, you do need to get the dip pretty fast or you'll hear the plate metal making funny crinkly sounds.

No.  That's a low duty cycle rig, one of the wave of lightweight low
duty cycle rigs that came out in the 1960s to make SSB affordable.
You probably have to be careful even just tuning it up.

If you want to run RTTY with a vintage rig which is admirable,
especially if mechanical equipment is being used, and I'm assuming you
are going to FSK the rig, the real RTTY way to do it, you need a high
power CW rig, or a RF amplifier built for AM.  That means an early
Hallicrafters amp for example, or the Heathkit Warrior or Chippewa.
Or something homebrewed.

Lift up a Warrior and you'll know right away.  It weighs twice maybe 3
times as much as the wimpy desktop amps sold 15 years later, the Drake
L4 perhaps being one exception.

It's the power supply which I think is a choke input, what you want
for continuous duty and a non-dynamic load, plus a plate supply that
can provide the plate current at power continuously.   Those amps
aren't sky high Peee Eeeee Peeee, a meaningless power specification
for suckers, but put in four 572Bs and it will sit there and put out
500 watts forever.  This is why RTTY ops seek them out.
