Hi Paul: just checked the data sheets for 807s. at 600v and 56 watts out Z 
is 10,000 ohm, in ab2 at 80 watts out Z falls to 6900 ohms.  any thing even 
close to those should work, problem is being able to find one.  good luck 
with the 807s in rf service, they can be very tough to tame use a shield 
around them up to just a little above the bottom of the plate.    Good luck
