I am looking for a substitute for a 6L6 that has the plate brought out
the top. I was trying to build a little Glowbug transmitter but was
having all kinds of problems neutralizing the the thing. I think I
would have better luck if I can separate the grid and plate circuits
from each other. I am considering an 807 as a replacement Suggestions
would be appreciated.

An 807 IS a 6L6 with a top cap anode connection. Any of the TV line
output valves will also do the job if you want cheap, the 6DQ6B works
well and has an octal base (The sockets for the 807 are rare).
6146 or 2e26 etc work well but will cost you more.

The 6BG6G / GA sweep tube is identical to the 6L6G but with a top plate cap.
