Full output for RTTY or FM has a roughly 4x higher transformer-VA
requirement than full output on SSB. Another consideration: for SSB,
one can get by with a simple capacitor-type DC filter, while for
semi-continuous duty modes like FM and RTTY, a resonant-choke filter is
indicated.

yes

My guess is that with 37w of drive you would need c. 4kV. The rated
drive for full ratings (4kV@1a) is 70-plus watts.
