an old video about making color TVs RCA.
 

Here's the entire film:

Lancaster CRT factory @ 12:20 is currently multi-use, built during WW-2 to manufacture CRTs for radar, later tv CRTs, transmitter power tubes, industrial power tubes, etc. Still today, many an obituary in the Lancaster paper lists of RCA as part of a proud employment history. Sometimes a job title is even mentioned.

I was always impressed by the wood cabinets RCA made at the Monticello plant @ 14:50, along the former Monon RR line, scroll down. http://monon.org/bygone_site/bygone/monticello.html

I wanted to reach back through the screen / time and slap that Engineer holding the FBT and say “HEY BUDDY!, that thing is going to overheat and bleed wax all over the place and burn up! Why don't you redesign it a bit better to last longer, like to keep moisture out a bit better?” :o
