Linear Question

[Wilson Lamb]

John is right.  The single, rugged, tube will do fine and likely last your 
lifetime.
The net is full  of people crying about bad 572s, so why bother?
HOWEVER, the simple little AL-811 is HALF the money for 3/4 the power and 
almost no one you talk to will be able to tell the difference between 600 
and 800W.  811-As are near bulletproof old tubes and also likely to outlast 
you, given any reasonable care.  I ran them in a modulator for a big AM rig 
when I was a kid.  Way overpowered at 1600V, zero bias, red plates.  Still 
have one of them, at least 60 years old, worked fine last week.

So for my money, the AL-811, with enough dough left over to buy a pretty 
nice rig or a LOT of beer!
