Does the vibrator hum? If not, remove it, turn it upside down and give it a few hand held slam downs on your work bench surface. Replace it back in radio and see if it will work. My radio vibrator use to (stick) constantly, so I went to a solid state vibrator that works great.

hi Mtneermik,
i don't do it for a living, but I have rebuilt the first generation radio 986067 for myself using as many original parts as possible (the old sugary filled electrolytic are rarely good).
your radio is probably the slightly updated 986443
they are 99% the same circuit

Chevrolet truck radio
1947-48-49-50 = 986067
1951-52-53 = 986443
both are interchangeable fit and if you ordered a radio in the later days for an earlier truck you would have received the newer model anyway.

... and when looking for parts, keep in mind that the Chevy radios appear to be nearly identical to the GM radios with dial faces that read GMC instead of Chevrolet.
GMC had different model numbers
example, 2233029 (but i'm not sure which specific years, but the radio looks like the 986067 two piece shell.)

i'm private message you links to documents
let me know if you have follow up questions
good luck

Not trying hijack this post. But Rick and 2ManyTrucks, seem to have a fair working knowledge of these old radios. I have the 986443, in my 53 3100. Ray Holland restored it for me my around 12-14 years ago. I stored it until installing it my truck in March of 2016. It worked great for about a year. Then, I would get a slight hum for awhile. Then it would go away. One day, I stopped by our bank. Shut the radio and the truck off. Got back in about 5 minutes later. Started my truck, turned on the radio and all I got was static. I can tune it to a few stronger stations. They come it alright. But, not nearly as well as they had before. Thinking it might be something wrong with the antenna, I bought another one. It sounds the same, when I hook it up as well. I happen to have another set of NOS tubes. You guys have any ideas? Again, I am not trying to hijack MtneerMike's post. I want to make sure that he gets his answers first.

Thank you all in advance for your advice and knowledge.

Do you get any static with the antenna not connected?

truckernix,

I don't get anything, when the antenna is disconnected from the radio. It's as if the radio isn't even on. Hope that answers your question. I really hope somebody can tell me what I am looking for. Even better, how to fix it.

Thank you for your help and advice.

So that is quite normal in that you shouldn't get anything with the antenna disconnected. If you have a set of NOS tubes, you could install them and you may get lucky. Otherwise someone would need to troubleshoot it on the bench.

truckernix,

Thank you for getting back to me. I appreciate your advice and experience. Hope to take the radio out of the truck in the next few weeks and see if I can figure out what the weak link is.

Thanks again.
