Genalex Gold Lion PX300B power triode tube with gold pins. Made in Russia. In Europe during the 1930s the GEC (Genalex)/Marconi-Osram PX4 and PX25 power triodes were considered the finest audio triodes of their day. In keeping with the tradition of Genalex to provide the highest quality tubes, New Sensor has released the Genalex Gold Lion PX300B audio power triode. This tube is the highest quality 300B type available and is considered to be an upgrade in any 300B amplifier.
