[NJARC] Tubes on video

[Ed Papson]

07/29/2015 

Over 35 years ago, before FREON Electronic Cleaning Agent products were banned, i made sales calls to 
a company in Harrison NJ that manufactured vacuum tubes. The product line was exactly like that in the first video. 
I never realized then that this was to disappear and regret not spending more time there.

How it's made: McIntosh MC275 amplifier: http://blog.thetubestore.com/how-its-made-mcintosh-mc275-tube-amp-production/ . 

And, if web difficulties don't make the page unreachable, watch how Shuguang makes vacuum tubes in Hunan Province today: http://blog.thetubestore.com/birth-of-the-shuguang-el34-b-vacuum-tube/ . 

Is it that different than production back in the day at RCA ( https://www.youtube.com/watch?v=J61hHMjxzC4 )?
