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

[Rodger Singley]

Michael,



That must be another descendant of the 6L6 which provided the basis for the 807 (and military 1625 variant).  I believe this is the first time I have heard of someone using a transmitting tube in a TV set instead of a sweep tube in a amateur transmitter, well done ?



The October 1956 issue of Radio and Television news contained a construction article for building a 2 meter grounded grid receiver preamplifier using a pair of forced air cooled 2C39 transmitting tubes which was also rather unique.

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
