I'd put an 811A in the PA slot and drive it with a modern xcvr of some sort.
You might even put an 811 in the osc slot and connect it in parallel with 
the PA.
Then a pair of 811s in the mod.
Sweep tubes aren't worth the trouble.
If you could find some dead tubes, you could make adapters from their bases. 
I just gave away a dead 838, but there are many 8008/872 etc, if you look 
Have you read the great stuff from

Is there such a thing as a sweep tube that can handle 1000 Volts
on the plate?   Best if it has 10 to 14 Volt filament, but will work
with other voltages.
