LL2771: Lundahl Choke

The LL2771 is a big dual-coil choke for high-current tube amplifier anode supplies. The choke has different core air gaps, which result in different inductance and DC current capabilities. The coil is wound using our standard high internal isolation technique with paper isolation between each copper layer. The core is an audio C-core of our production. LL2771 is well-suited for choke-input power supplies.

The LL2771 is available in 4 versions.

• 0.7H, 2A
• 1.5H, 1A
• 3H, 1A
• 6H, 500mA
• Silicon-iron (STANDARD) core material

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

Dimensions - 150mm x 105mm x 90mm
