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
