Hey guys, I just had this given to me by a friend. I don't know if it works but it was sitting outside in a pile of junk and has been rained on. I spotted it from about 100 feet away and had to check it out and my buddy said I could have it. Does anyone know if it would be worth messing with to get it going? Has anyone used one of these? At the very least I am going to clean it up and display it on a shelf. Any and all replies welcome, thanks!IMG_20180119_095013869.jpg

super useful tool for troubleshooting.

If you do radio repairs, it's a great item to have.

My opinion would be that it's worth it to restore it, but i restore everything that comes into my shop LOL.

cool find!

a scope works good finding where the signal starts and stops. the 147 is good if you have a noise problem in the TX or RX, I have 2 of the 147 testers and would not take for one of them. I either use the scope or tracer depending on what I am looking for in the radio.

shadetree, i would advise against turning it on.

you should replace those electrolytics before you do so.

that tube that shows out the front is hard to find if i recall correctly, and you would hate to blow it out with a shorted cap.

having been out in the elements means that any paper cap has absorbed and dissipated so much moisture that there are bound to be leftover elements and minerals that could cause problems.

from the pics it looks like you just have to replace the paper cap on the bottom and that can cap on top.

no need to try to find another can cap, just buy individual axial lead electrolytics and wire them in place of the can cap.

after that, and a good cleaning including contact cleaner, and you should have a good unit.

oh, almost forgot, be sure to check all the wires for green corrosion since it's been outside.

Thanks LC, I was hesitant to plug it in and now I am glad that I didn't. Honestly I was surprised to find tubes in it, I didn't realize it was that old. I am just now reading the manual and it looks like this was a kit based on the assembly instructions.
