Finally, we finish the Hallicrafters S-40 and ship it back to Arthur. I am really sorry it took so long, I hope they enjoy it.
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.
Progress is made on the K1SVC Hallicrafters S-40.
This video shows the tear down of the chassis. We remove the IF Cans, Power Transformer and Variable Tuning Capacitor.
Those of you that have been to my site before might be a bit confused. This site used to be called KBØASQ after my Amateur Radio Call Sign. After dragging my feet for awhile, I requested that the FCC reassign to me my original Call Sign WDØDXD.
It is the first call sign I had when I got my ticket in 1978. It wasn’t reassigned after I lost it when my novice license expired after the 2 year period that they were good for back then. They changed the rules and allowed you to reapply and keep the novice license if it had not been expired for more than 1 year or 2 (I don’t remember how long it was). So I reapplied and got a new sequential license.
Nothing has changed, just got the old call back and should have some new content ready for you soon.
We take on another Hallicrafters restoration. This time an S-40. Most of the restoration will be cosmetic on this one, but we will have to check some resistors and replace some electrolytics.
This video gives an overview of the condition of the unit and I also show a S-40B that we will be working on at the same time.
In this video we finish K1SVC’s S-38. I show how we replace the speaker, and then run into trouble, the new speaker doesn’t clear one of the tubes, so we go to plan B. Then we install the new back and make a new bottom label.
Finally, we put it back to work listening to some shortwave broadcasts and a SSB transmission. Next step is to box it up and send it back.
