Assuming a shorting DCR of say 0.2R at the 4 Ohm winding, the 16 Ohm output will appear loaded by 0.8R parallel to the speaker.
Consequently output power could be up to 5% of nominal.
But as the tubes will see a very low Raa, which allows for only little voltage swing, output power should be much less than 5%.
Nevertheless a few hundred mWs of output power seem possible.
