LL2743: Lundahl Anode Choke

The LL2743 is an anode choke for tube amplifiers. The choke is built with two coils and uses our grain-oriented 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

The LL2743 is available in 2 versions.

• 64H, 70mA
• 50H, 90mA

(N.B. Adjusting the airgap adjusts the DC current and inductance. This is done at the Lundahl factory.)

There are further 2 versions depending on what C-core material you require.

• Silicon-iron
• Amorphous-iron (AM)
