LL2742: Lundahl Choke

The LL2742 is a 2 coils choke for tube amplifier anode supply. The choke is available with different core air-gap, which results in different inductance and DC current capability. LL2742 can be used in choke input and cap input applications. The coil is wound using our standard high internal isolation technique with isolation foil between each copper layer. The core is an audio C-core of our own production.

The LL2742 is available in 6 versions.

• 4H, 500mA
• 6H, 350mA
• 10H, 200mA
• 17H, 250mA
• 24H, 175mA
• 42H, 100mA

(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)

Dimensions - 95mm x 75mm x 50mm
