12" crt

[Geist]

Hi All;
Thank You to everyone, I had no Idea that there had been so many 12" Sets made.. Since Except for the TRK-12, and it was not magnetic deflection, like the post-world war 2 TV sets.. I had not heard of many 12" Crt's.. I guess that the 12" was not as popular as the larger 14" to 16" at that time period.. Are the 12" CRT's hard to find, compared to the 10BP4.. THANK YOU Marty

The 12AP4, used in the TRK12 is magnetically deflected.

others like magnavox , garod , westinghouse , andrea too used 12" tubes , 12L4 being used a lot , philco also had that weird one 12wp4 ? , dumont had 12qp4 which is simular to 12lp4 just a little shorter.

Yes, in my experience they are. Especially the aluminized 12KP4.

Hi All;
My mistake, I must have confused the Trk 12 with the trk 7 or one of those pre war sets, with the 7 inch screen..
THANK YOU marty
