Silly Job Title: Cable Connector. I am the Cable Connector!

I got some feedback from a viewer about an old project: 1-Transistor Radio | Project 5/10 | Maxitronix 10in1 | Learning Electronics In The Lab With Jay Jay. The observation was that there was a discrepancy in the instructions. So in this video I redo the project to see if we can get the radio to work if we wire it the other way. Alas, we don’t, but it was worth a shot. Thanks @Panthraz for your suggestion!
