Recover electronically signed radio

hi everyone and welcome to another episode of mr. Carlson's lab today we're going to do something just a little bit different I have a radio from the late 30s era and what we're going to do is just replace the components that absolutely need to be replaced under the chassis so we're just gonna replace the components that are stopping the radio from working just the failure points so what I'm going to do is bring the radio up slowly on a current limited isolation transformer and variac supply just to make sure everything is nice and stable and after that point we'll start the diagnosis and troubleshooting procedure together so it should be a lot of fun let's get started here's the radio that we're going to diagnose and get working today so one by one will replace all the components that's stopping this thing from working so we'll trace down all the faulty components and slowly bring this thing back to life and we'll see just how many components we have to replace to actually make this thing work now I have noticed that somebody has been in here at some time and they've replaced the line cord I have a schematic for this thing and I'm pretty sure I know why they replaced that line cord because some people probably got a pretty good shock off of this thing over time and I'll show you exactly why the build of this radio is just a little bit different than all American five and all Americans six radios to the point to where they've actually tied one part of the line cord directly to the chassis and it's a direct wire rate inside right through the switch directly to the chassis so if you were to plug this thing in backwards with the original non-polarised cord the chassis itself would be live arenal with 120 right on it and of course having 120 on it if you were to you know come across that touch just the chassis of this thing that would be I guess you could say a very enlightening experience definitely nothing that you would ever want to come across so we'll take a look at that here as well so what I'll do is I'll turn the radio around and we'll take a look at the back side here in just a moment it looks like the dial moves so there's no problems with the dial the on/off switch clicks and it feels pretty smooth now there are two bands on this radio there's a broadcast band and on the bottom it looks like it goes from the top end of the broadcast band through the hundred and sixty meter band right to the top end of the 80 meter 75 meter band rate up to four mega cycles or four mega Hertz and today's speak so it has a bit of a shortwave area in it and it also has a broadcast...
