Japanese roundie #2

[eberts]

All the picture tubes in the above sets were made in the USA.
Jap made tubes except for the trinitron were not common till the 70's when they started importing 19" and below completed color tv sets. Any thing over 19" even if it was a Jap set had a USA made tube in it till about the late 70's, early 80's.
The 27" Sony Trinitron tube was made and assembled in the USA of USA parts except for the electron gun.
Later on Jap tubes showed up in more sets up to 25".
The poorest quality tubes were made in Tawain. They would lose vacuum after 2 years from the poorly made frit material sealing the panel and funnel.
Tubes made in the netherlands by Phillips were also junk.
The American made tube has never been surpassed in regard to quality, durability, and very long service life.
