307-A IS A PENTODE MADE FROM WESTERN ELECTRIC AND PRODUCED FROM MANY FACTORIES LIKE SYLVANIA , KEN-RAD OR RAYTEON.

iS A TUBE USED ON AUDIO PARTS OF MILITARY EQUIPMENT FROM 2ND WORLD WAR

NOW TUBES HAVE QUITE 80 YEARS OLD THEY COME FROM OLD MILITARY SPARE CRATE

SO MAY HAVE SOME LITTLE SCRATCH OR COULD NOT BE SEAMS LIKE PULLED OUT FROM BOX

BUT THEY ARE VERY RARE AND WORKS WELL FOR THEY AGE

SELECTED BY TV-7 ( REBOXED ) 

HOW IS POSSIBLE TO DECLARE "NOS" A PRODUCT 80 YEARS OLD ?

IT COULD BE REAL TO DECLARE "UOS" USED OLD STOCK.

PRODUCTS MANUFACTURED FOR THE WAR TIME AND SURVIVED FOR AN HALF CENTURY

 IS PART OF THE VINTAGE OR THE HISTORY

 IS NOT A MODERN OR RECENT PART

 THIS SHOULD BE CLEAR IN MIND, WHAT YOU BUY HAS 80 YEARS :-)

PAIR #5 26.9/28.5 mA

All the tubes have been tested with the TV-7 tube tester and with digital instruments.


It is correct to say this, if you want something different you have to resort to recent productions, Chinese, Russian, and others, these objects for their age it is already a miracle that they work.

Therefore the valves are purchased with the AS-IS rule, "SEE AND LIKE" , if you do not agree with this rule it is better not to buy, in order to avoid useless stories.
