Johnson 223 Resto, part 2...

 This is the 2nd phase of this restoration... I picked this old Johnson CB Base station up at a local yard sale. It looked like it was at the end of its road. I have a soft spot for these old rigs, so decided to give it a face-lift. It needed all of the typical stuff....caps, a handful of resistors, switches & controls needed service, tube sockets and pins cleaned, and few crystals that had drifted out of spec, a knob bright, the mic needed a major cleanup, and she got a full alignment. Here's a few pics and vids...





This was one of the donor radios I used for crystals and knob brights...


I also salvaged the channel selector to replace this mess...


These crystals are almost unobtainium, these days...


More donor radios in the shop floor :-)  

Chassis cleaned...I'm pointing where the rectifier tube once was. It now has a solid state rectifier...

Slowly coming together...

Filter cap replaced under the chassis, the old can-type cap is still up top for looks :-)

Various other caps replaced...

Installing new feet on the cabinet...


Pop riveted from the inside...


 Tuned up, nice and clean tx audio!

EF Johnson Messenger 223 Restoration

 Here's another yard sale find...I can't help myself. This was one of the dirtiest, worst condition rigs, I've done in a while. It had set in a damp barn for decades, and the chrome had bubbled up a little. I'm still looking for a junker with a good knob and decent faceplate, but it's pretty good, otherwise. After a major cleaning, I replaced all of the electrolytic caps, a bunch of resistors, removed a dirt dobbers nest, and aligned it. Wow!! What a hot receiver this old girl has. Another classic saved from the landfill, and on my shelf in the collection. Here's a few pics...the first 3 are post  resto, the rest are of this dirty beast during resto. Check out the dirt and caps :-) How do radios get in this condition? I guess I love radios too much!
