Well, I build to match my tubes, not because it is efficient or 
inexpensive, but because it is esthetic.  I am building a linear for the 
S-Line using a single 4-1000A.  Not because its the best way to go, but 
because I can think of no better tube to have behind a window to look at 
while sitting in a cold shack.....well, cold before I turned on the Linear.

I am using the window out of a microwave door so that the entire inside 
of the linear is visible from the front.

I am still looking for something to use the 833A in because it is a 
humongus beautiful tube to look at.  Someone answered this thread 
suggesting two 4-125As modulating the 833A and that has a good "look" to 
it.  I could use a "hurricane" candle chimney for a cooling chimney on 
the 833A.

I build for the beauty of the instrument.  If I could figure out how to 
put a "Jacob's Ladder" on the top of my transmitter without causing all 
manner of interference on the receiver I would probably try it...#8-)  

We are the wizards of the world and we should make it look impressive 
and complicated to keep the riff raff out.....#8-)  Lots of brass, 
mahogany, glass and glowing filiments....thats the ticket.
