807's are really nothing but a slightly modified 6L6G.

They even share the same cathode and other elements as some 
productions of the 6L6, and even have the same heater 
current.

The 807 brought the anode out the top to increase voltage 
breakdown and make a better RF path and had some variations 
in insulation and envelope, but it is still basically a 
slightly modified 6L6.
