which is either ham or cb linear. Rollie

OK, I got an old linear that I acquired from my late FIL about 20 yrs ago.
It's been in cool clean storage ever since and I'd like to get rid of it.
I
tried to sell on ebay till I got mucho alerts to the effect ebay no liking
CB linear listings. I pulled it. I don't know much about radio, but I'm
sure it was a CB linear cuz he never had a ham license. I was advised by
one helpful fellow that I should list it as a ham linear and make no
mention
of CB. That makes sense, but I pride myself on being very accurate and
honest about what I sell and so would like some help identifying this
particular piece of hardware, it at all possible.

It has no brand name on it, so I suspect it's a homebrew. It's a very
nice
job if it is. It has a 2" high chassis box with one vacuum tube and a
pretty good size transformer mounted on top. A 4" high full cover over
that
is machine perferated on 3 sides for cooling.

Transformer: GRAND 11-2206A GT-6974 7578049
vacuum tube: 6805/EL84

On lower front lower chassis, it has an ON/OFF and STDBY switch and one
red
light. The meter is a Sonar brand:

S units -- DB
Output 0-30+

Rear lower chassis has IN and OUT antenna jacks and a ground wire terminal
and of
course, an AC plug. Overall dimensions with cover on are 6"H X 7"W X 5"D.
Weight
approx 6-8lbs.

I don't know if anything can be determined by the above info, but any help
would be appreciated. I can open her up all the way, if that will help.
I'm not real savvy on radio, but do know basic electronics and can
identify
different components. Thank you.
