The following information was sent directly to me by Joao Lopes, CT2HME.
He suggested posting it for the group.
73, Dan, N5AR ( who now is much better acquainted with the GS35b, Hi)
"Power output will be about 2.5 KW on HF.
Tube is quite inexpensive when compared to the 8877. I do not know why
so
few HF amps using this tube are made. I would expect US amp makers to
look
at this tube for legal limit HF amps. But they don't...
Where can you get the tube? Simple. I got 2 GS31B from a UT7 callsign in
Ukraine but I lost his contact. He has a page on the net and he is a
decent
honest person. I sent him the money (wire transfer) and he sent me the
tubes, brand new and well packed. Someone must have his address
somewhere.
While I don't find it, try this:

Here are some pages I would advice you to visit:
