I forgot the old 813.  I have 3 of them up on the shelf and keep looking 
for more.
I used to run the "old legal limit" with a pair of them as you 
describe.  I ran into a guy on 40 a while back who claimed he could get 
2400 PEP out of 4 of them. I don't know if his amp was a monoband or 
covered all of the HF bands.

I see the GS-31 (1KW), GI-46 (1KW), and little GI-7B are at reasonable 
prices and seem popular.  With the removable anode coolers on this 
series and the popularity of converting the old Dentron MLA2500B to a 
pair of GI-7Bs that no one has machined a transverse version of the 
cooler to make them even more compatible with the old 8875s I think they 
used.

There does seem to be a lot of interest in what tube(s) are in homebrew 
amps though.
