That is the same efficiency as with a 8877 at that voltage.
It will be much better at higher anode voltage.

Well, I have finally completed this project...All electronic circuits 
perform faultlessly...I am using a russian GS-31B in this project...I 
will later replace it with a GS-35B....Running conditions as 
follows...2800vdc under load @ 900ma with 60 watts of drive produces a 
tad over 1300 watts carrier output....This is close to 55% efficiency, 
about what we can expect from these tubes...
