Due to the number of new tubes fabricated during and immediately after World War 2 it is very difficult to set the exact time of manufacture. Many were discontinued, others remained until 1960. Beginning with this page is a selection interesting radio tubes from that era. Typical characteristics: All-glass constructions and metal designs. Often special bases.
