Great thread, great idea!

Where to get schematics

Start at my page: https://www.audiophool.com/Finding Manuals and Schematics.html - I have links to many online sources, and would welcome any additional ones.

Sams Photofacts are the best for 1946 and later - they have a schematic, parts list, photos to identify parts. I have a thousand or so, most pre-1960 not a very complete collection. The online index at http://www.samswebsite.com/photofact/pf_search.asp Best index (going back to the '20s!) is here: https://plymouthcolony.net/starcity/radios/files/verify.php?file=uslocator.zip - it searches not only Sams, but Beitmans and Riders as well. Beitmans and Riders are available online at http://www.nostalgiaair.org and https://worldradiohistory.com/Beitman-Manual.htm respectively.

Now that you have the Sams folder number, where to get it? Try your library first - many can get copies from a central library. It's $25 or so from Sams (pre-'64 ones are $7), but there are lots of copies around - remember, every TV shop had a subscription back in the days when things got repaired. I have a few to sell (money goes to the Antique Wireless Association): https://docs.google.com/spreadsheets/d/1I7uGU7n4QaLXPD2R2orRBGoio4B4GqkDw_iOF5b_WaA/edit#gid=0

"I was at an EZ Pawn store today in Houston today looking to see what they had and decided to poke my head in an electronics repair store next door. Well, i was greeted by a tube tester on top of a cabinet full of tubes and a repairman who said that tube type equipment is their favorite type of equipment to repair. Haven't had anything worked on there yet, but am thinking of taking my Duynaco tuner there fr a recap job.
