I'll  agree re the GS-35B...certainly a bargin at the  moment.




Gentlemen, I have found that a single GS-35B used with the same power  supply 
as with a pair of 3-500's will make about 100 watts more power output  with 
100 watts drive.  Should you drive the GS-35B with more power they  should 
outperform the pair of 3-500's with better linearity.  The GS-35B  tube will 
take 
1.2 amps anode current vs only 800 mills for the 3-500's in  linear operation. 
 At first the GS-35B was touted as the poor mans 8877 so  I picked up a few 
of the GS-35B's myself.  Unfortunately they do not  perform as well in the 
output dept. with the same amount of drive as the 8877,  probably down by a 
factor 
of 35-40% for same drive levels.  However, no  problem making LEGAL limit 
with 100 watts with the GS-35B, but with the 8877 and  the same 100 watts 
drive, 
we are talking about 600 to 700 watts difference which  easily exceeds legal 
limit.  The GS-35B is certainly more rugged than the  8877 if that is one of 
your concerns.  This is why the contesters like the  3CX1200 vs. the 8877.  
Also, like the 8877 the GS-35B is a very stable  tube.  All and all it is a 
GREAT 
tube for the money!
