K1SVC Hallicrafters S-40 Restoration – Part 6
In this video we show the S-40 with the dials mounted and the sensitivity switch replaced. We also show some other projects that have slowed the progress on the S-40.

In this episode we re-mount components on the top of the chassis and wire them in underneath. Then we trouble shoot voltages and finally it comes alive!
In this episode, we check the caps and shotgun the resistors. Sorry about the audio, I need to find out what is causing the ringing noise.
In part 3 of our Hallicrafters S-38B restoration, we strip the chassis of it’s components and media blast it. Then we proceed to paint it with Rust-Oleum Stainless Steel appliance epoxy.
After that we start to remount the components onto the chassis.
Next episode we will work on the IF cans and start to recap the chassis.
In part 2 of our Hallicrafters S-38B restoration, we will media blast the cabinet and then prep and powder coat it with Black Winkle powder coat from the Eastwood Company.
We show the steps we take to prep the metal after we have media blasted it and how we apply the powder coating.
The process works pretty good this time, but we do have a few blemishes. We decide to live with them on this restoration and hope we learn some valuable lessons for the next time we use this process.
I think you will agree that at the end of the process we have made considerable improvements to the case of the radio.
Next episode we will try a new process to us on applying the decals to the front of the case.
Just to show that we like the old as well as the new, we have started a restoration project on a Hallicrafters S-38B. This particular radio we purchased off of Ebay a year ago. It is in pretty rough shape, so this should be interesting. Whene we got it, it had shredded newspaper in it for packing. We didn’t get charged extra for the dead mouse living in the newsprint. (Tip, when storing old radios, don’t fill them with newspaper, great home for rodents and it really holds in the moisture.)
The case has so much rust on it, there is no way way can get away with just a touch up paint job. So we are going to try a different approach, powder coating. We found some crinkle powder coating from Eastwood that we are going to use. If successful we should have a very durable finish that will last for a long time.
The biggest challenge on this one will be the top of the chassis. It has plenty of rust, so my first thought is, we will have to probably paint it. I don’t usually like to do that, but I think this one will require it. We will know more once we get the navel jelly on it.
The speaker looks like it has some tears in it, but it also looks like a good candidate for repair. Other than that we will recap what needs it and I think I might put an upgraded BFO circuit in it.
So take a look at what we have and follow along as the the fun begins.
