Hi nb, I went to www.cbtricks.com and the only Sonar linear they list is
the BR-21. They say it's a 30 watter made for their ham tranmitter. It can
also be used for CB if the correct capacitor is in and the correct inductor.
See the schematic they have. Hope I've been some help. 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.
