Description
Production for the Marconi Osram PX4 kicked off in 1929! Personally it is the best triode ever made, offers sweet and smooth sound.
Three years later the PX25 was launched and the Olympia Audio Show and those I have for sale are dated about that time! The PX25 offers detailed sound like no other tubes! The PX25 balloon is the earliest model of the PX25 and suits all vintage and modern amplifiers. Honestly speaking the PX25 PLAYS BETTER THAN A WESTERN ELECTRIC 300B!
Both PX4 and PX25 have been tested and are in full working order
Can sell in pair or quartet.
