Filament Transformers
Osborne designs and produces high impedance and unregulated Filament Transformers. An unregulated filament transformer supplies a specified voltage and current to the filament of an electron vacuum tube. High impedance filament transformers are designed around a tungsten tube filament. Osborne often works with our clients to increase the life-span of their vacuum tubes through the use of a regulated voltage supply.
Let’s talk about your project.
