K1SVC S-38 Hallicrafters Restoration – Part 3
In this video we replace the capacitors and resistors in the S-38. Next video we will start to work on the case.
K1SVC S-38 Hallicrafters Restoration – Part 2
In this video we clean and polish the S-38 chassis. We start out using Brasso and then move to Mother’s Mag and Aluminum Polish. I also clean the trimmer caps on the IF cans.
K1SVC Hallicrafters S-38 Restoration – Part 1
Arthur has asked me to restore two of his father’s Hallicrafters receivers. His father is K1SVC and his name is also Arthur. He sent me a S-38 and a S-40.
In this video I show the condition of the S-38 and S-40 and start working on the S-38.
By the end of the video I have the S-38 chassis removed from the case and strip the top of it of components to prepare for cleaning.
The next video will show the cleaning, polishing and reassembly of the chassis.
Hallicrafters S-38B Restoration – Part 6 Final
In the final installment of our restoration We show how we made the replacement knobs and give a final overview of the completed restoration.
One point I want to clarify. In one of the videos I misspoke and it sounded like the chassis was not hot. What I did was make sure it wasn’t hot when the power was turned off and then I also installed a safety cap to make sure if the filter cap failed it would not fail to a short.
Over all we are very happy with the outcome and think we did justice to this restoration. We learned a lot and hope to apply those lesions to future restorations.
At our local August club meeting, we presented the restored radio to our friend and he seemed to be very happy with it. We have several more Hallicrafters radios to restore, so look for future videos on those.
Hallicrafters S-38B Restoration – Part 5
In part 5 of our restoration project, we align the radio and build, test and install the new BFO. We also install the chassis in the case and finish up most of the decal placement.
The BFO design was taken from http://www.flashwebhost.com/circuit/bfoceramic.php. I used power from pin 4 of the IF amplifier.
The next and final episode will show how we make the reproduction knobs and I will give you a final overview of the completed project.
Hallicrafters S-38B restoration – Part 4
In episode 4 of our Hallicrafters S-38B restoration, we finish the electronic maintenance. I show how we replaced any out of tolerance resistors and caps.
We also rewire the power cord to make sure it gets plugged in with the the hot side switched.
The speaker is repaired and we turn it on for the first time.
Hallicrafters S-38B Restoration – Part 3
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.
Hallicrafters S-38B Restoration – Part 2
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.
Hallicrafters S-38B Restoration – Part 1
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.
