Not very well unless you want to get creative in the tank circuit. That
tube has very high output C. There are much better choices for 6M. IMO
it is pure overkill. If you wanted a bullet-proof 5KW amp then that would
be a different story.

If you want a legal 1500W, an 8877 will work just fine with a low noise
muffin fan. I have converted Dentron DTR-2000L's to 6M and at 1500W and
the muffin fan the tube never gets hot. You can also get away with much
lower Ep (2500V) and save $$ on parts.
If a few less watts is acceptable, say 1300, an SB-220 conversion is the
way to go. The fan is very quiet.
