Lundahl Chokes

We have a wide range of chokes and inductors for tube amplifiers, ranging from anode choke LL1667 (operating current from 5 mA) to filament current choke LL7233 operating at 3.4A
Our chokes are of a single C-core type. Using C-cores with well-defined air gap results in an almost constant inductance throughout the operating voltage range.
