[Boatanchors] sweep tubes (was Re: Galaxy V)

[Jacques Fortin]

Hi Mike,

First came the 807, then came the 6L6G, then the 6BG6G, which is a 6L6G with
a top plate connection (intended to be used as an horizontal deflection
amplifier in TVs).
So the 807 and 6BG6G are identical, except for the base.
I once used a 6BG6G in a Wireless Set #19 MkIII, in place of the 807 final,
with a socket change...

I did the opposite. I used a transmitting tube in a TV. In our 17" RCA from
the early 1950s, the 6BG6G sweep tube went bad. Comparing to an 807, the
insides looked the same. Checking tube manual data, the two tubes were
identical to very close. I wired up a 5 pin to octal adapter, and it worked
just fine until the TV was scrapped in the 1970s. I found it quite
interesting that the 6BG6G (not 6BG6GT or later) and the 807 are probably
the same tube with a different base. Anyone know this fore sure? At the next
hamfest, dig around the boxes of tubes and pick out a 6BG6G and check it
out. --Mike, WV2ZOW
