Telefunken EF86 DIAMOND Military BWB TUBES

 

"BWB" MILITARY EAGLE

The TELEFUNKEN DOME-TOP TUBES WERE THE "OLDER BETTER" TELEFUNKEN TUBES, MADE IN THE 1950'S AND EARLY 1960'S.

THE BWB SOURCED THESE OLDER 1960'S TUBES in the early 1970's from Telefunken factory stock WITH THE DOME-TOP AND 

RE-LABELLED THEM "BWB" and REPACKED THEM AFTER EXTENSIVE MILITARY TESTING.

Telefunken didn't make EF86 tubes in the 1970's as the Telefunken Factories had long ago shut their doors

These are BWB CERTIFIED for TOP specifications, not only meeting but EXCEEDING Telefunken's Data Sheet requirements.

THEY THEN labeled THE "BWB 448" GERMAN MILITARY DESIGNATION "EAGLE CREST" AND REPACKAGED THE BOXES IN 1970's.
