Sure - they work fine in amplifiers like the W1SL and the W2GN. Expect 
about 500W from the pair, but with stable voltages they can give a very 
clean signal.

'The VHF/UHF DX Book' is probably the best source of information for VHF 
power amps using this size of tube. It's still available from ARRL.
