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 :-)
All the tubes have been tested with the W20 Max Funke tube tester and with digital instruments, as you can clearly see in the photos.
Due to the age of the valves which are around 80 years old, sometimes the resin which holds the glass bulb to the socket loosens and the valve moves.
The valves that have been verified with movements during the test are marked with an X, but this does not exclude that after some time and a little heating, they cannot move.
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.
