JULIUS FUTTERMAN
The Father of OTL Amplifiers
Julius Futterman is the first man, in 1954, to create an OTL amplifier, a tube amplifier that needed no output transformer. Over the next three decades Julius's circuit's unique ability to express musical beauty virused the world establishing him as a Master of the thermionic arts.
