Tube anode choke LL2743-70mA
The LL2743 is an anode choke for tube amplifiers. The choke is built with two coils and are using our own grainoriented silicon-iron audio C-core. The coils are made using a low capacitance coil winding technique. The two coil structure greatly reduces the risk of picking up hum caused by external magnetic fields from e.g. mains transformers. The LL2743 is available with different core airgaps for different DC currents on request.
