Description

This tube was made in Holland about 1924-25, in an attempt to sell tubes in the US. GE/RCA filed four patent suits against Philips. Both companies realised that years of litigation might follow and agreed to a compromise: GE/RCA would share patent rights and Philips would stay out of GE/RCA territory.
