LL2746: Lundahl Interstage and Line Output Transformer

The LL2746 is a three-section dual coil C-core tube amplifier step-up interstage transformer. The coil is wound using our low capacitance, high internal isolation technique with internal multilayer isolation foil where layer-to-layer signal voltage is big. Winding order is chosen to minimize destructive capacitive energy buildup between primary and secondary sections.

The LL2746 is suitable for single-ended circuits only. (The air-gap is adjusted during manufacture to suit)

• 30mA Single-ended

(N.B. The purpose of the airgap is to accept the DC current of the output valve without saturating the core, leaving enough headroom for the sound signal)

There are further 3 versions depending on what C-core material you require.

• Silicon-iron (STANDARD)
• Amorphous-iron (AM)

And a further 2 options depending on what wire you require.

• Copper
• Silver (Ag)

Turns ratio

• 1 + 1  : 2 + 2

Overall size including pins - 95mm x 75mm x 50mm
