Vintage National Union Radio Vacuum Tube Made in USA:
$75.00
This is a genuine vintage vacuum tube manufactured by National Union in the USA. Labeled as a 'Long Life Tube' for renewal service, this component features a classic black base and a dark smoked or carbonized glass envelope. National Union was a significant American manufacturer during the golden age of radio and early television electronics. These tubes are highly sought after by vintage audio enthusiasts and collectors who restore antique radios, amplifiers, and testing equipment. The tube appears to be in very good physical condition with intact pins and clear labeling, though its functional performance hasn't been tested. The 'Made in U.S.A.' marking confirms its heritage and build quality from the mid-20th century electronics era. Perfect for display, restoration projects, or as a period-correct replacement part for vintage electronic gear.
