Description The RCA tube 6E5 is the first Magic Eye, designed by Allen Balcom Du Mont (born Jan. 29, 1901 in Brooklyn NY, died Nov. 15, 1965 New York NY). Starting 1924 as an engineer for Westinghouse Lamp Company, Bloomfield, NJ, developing manufacturing and testing equipment for vacuum tubes. His first patent was: Aug. 21, 1925 serial no. 51,561 for "Mount for Radiotubes", patented July 9, 1929 as 1,719,968. He had achieved many more than 100 patents but for the Magic Eye the essential one was: Filed Sept. 18, 1934 Serial no. 744,498, patented June 20, 1939 as 2,163,256. Part of the patent text: "A cathode ray tube having beam producing means comprising a concentrating cylinder, an insulating cylinder having two holes there-through, a spacer connecting said insulating cylinder with said concentrating cylinder, a tungsten wire filament threaded through the holes in said insulating cylinder, a molybdenum wire secured to said tungsten filament, and an ocyde coating on the tip of said molybdenum wire. 2nd: A cathode ray tube having a fluorescent screen, means for producing a plurality of beams comrising a plurality of concentrating cylinders ..."

RCA followed with a 6G5, registered February 21, 1936. Still in 1936 RCA introduced the 2E5 and 2G5 electron-ray tubes so that also sets with 2.5 volt filaments (then actually outdated) could be equipped.

Hello, is possible change a 6E5 with a 6E5C ?

Please, let me know!

Thanks a lot!

Bye

The normal 6E5 is 6 pin base and "bulb" shape.

The 6E5C is straight sided and octal base.

 

So if you change the tube socket or there is space for an octal to 6 pin adaptor (by moving the existing base which usually isn't on the chassis), then yes it should work. The pattern is the same and the sensitivity should be similar.

  1 Gentlemen,

There is a reference to the Sylvania tube number 6E5 associated with the photo in tube id=2111. I respectfully and totally agree that in my Sylvania News Technical Section Vol. 6 No. 1, is the complete article with photograph of the NEW tube as it was introduced by Sylvania (in the United States) in January 1936.

With all due respect, I have no knowledge as to when the USSR would have introduced their first "visible tuning indicator".

The original Sylvania tube used the ST-12 shaped bulb with the small 6-pin base - as illustrated in the present tube id. The pinouts are identical to those of the Sylvania.

I have recently completed two (2) adapter sockets which now allow me to test the "rimlock" tubes, and the european F8, G8, and Y8 base. I am presently conducting tests with an adapter I have created which will permit testing the European sidepin octal tubes (DIN 41565) on the Hickok 752A tester.

I have discovered there are some limitations with current draw to properly test some of the full-wave rectifiers.

Respectfully,
Robert
