REPLY:

I would recommend against using a GS-35b. Their efficiency is low
compared to other types. I and several others have obtained
efficiencies in the range of about 50%, compared to about 60% for an
8877 and other comparable tubes. 

Aside from poor efficiency they do seem to work well so that is not
necessarily a show-stopper, just something to consider.
