FA: Sonar FS-23 Tube CB Transceiver Looks Like Collins MINT
 

I have a Sonar tube CB for auction on eBay. The URL with pictures is

and the description is

This is a near-mint example of the venerable Sonar FS-23 thirteen tube two
transistor 23-channel CB transceiver. Features include 12V/120V operation, a
continuously-tunable receiver section (RIT) and 23 crystal-controlled transmit
frequencies. Tube complement is



1 RF Amp
6DS4

2 1st Rec Mixer - Squelch 6EA8

3 16MC Osc. 6AU6

4 1st Sythesizer Mixer - 4MC Osc. 6EA8

5 2nd Rec. Mixer - 2nd Rec. Osc. 6EA8

6 1st IF Amp 6BA6

7 2nd IF Amp 6BA6

8 Noise Limiter - Det. - AVC 12AL5

9 Speech Amp - Friver 12AT7

10 Output - Modulator 12BH7

11 2nd Synthesizer Mixer - 6MC Osc. 6EA8

12 Buffer 6AU6

13 Final 6BH5



This would make an excellent basis for a 10 meter AM conversion, as the
chassis is very open and easy to work on. I originally bought this because the
case resembles Collins S-line accessories (for example the 516F-2 or the
312B-4) and I was going use the case to build a custom
speaker/SWR/station-control accessory to match my S-line equipment. Well, like
many projects this never bubbled up high enough on the "to do" queue, and I
sold the S-line before I ever got around to it. Would be a great project for
some other S-line owner however. Or it could be used for an excellent-sounding
(can't beat tube audio!) CB base or mobile rig as intended...

Unit includes AC cord, microphone and I'll include the DC connector if I can
find it.

Closes January 30, 2005.

Thank you.
