Looks like a serious amp. Maybe about 12W is possible class B? Or perhaps as much as 25W with some distortion. About 10W in class A push pull.
I wasn't familiar with the 6F6, but it seems to be a higher power version of the 6V6, but less than the 6L6. I've used 6V6 and 6L6.
Edit
Reading up more it seems the 6F6 is the oldest of those and in late 1930s was replaced by 6L6 and 6V6, the 6V6 being a derived lower power version (0.5A vs 0.9A heater) of 6L6. The 6L6 is still produced and the 6V6 was very popular. So I guess that's why the 6F6 was unfamiliar to me.
