1952 ABANDONED VACUUM TUBE RADIO REPAIR - WHY DID THEY QUIT? RESURRECTION OF A EMERSON 641B [4k]

This radio seems to have a history. It looks like it worked for about 10 years, had a little work done in the early 60s, and then in the last 5 or more years ago, someone was working on it but apparently gave up! Let's see if we can find out what caused that person to give up, and if we can carry the repair through to a playing radio once again.

Playlist for this radio:
   • Emerson 641B  

See the checklist which appears, when status changes, for tracking what is discovered that needs addressing in Red, followed by Green when resolved.

(UPDATE: I have repaired and restored this radio, see playlist) Someday I may electrically restore this radio, if so, a playlist has been created to help link the restoration video with this resurrection video. Turn on notifications to see it.

This is not instruction, it is for entertainment for people like me who enjoy watching projects and the experiences gained. If you attempt to do some of the things in this video you are at your own risk. I am using special tech-bench safety equipment not detailed here so don't take for granted you can just plug these old items in safely without them being checked and repaired correctly. Check out the link below to Mr Carlson's Lab video below.

Thanks to shango066 for championing the approach of "fix it first", before mass re-capping. Had the person who attempted this repair used that approach, they would have had a much better result. See shango066 for many examples of that approach.
