LL1689: Lundahl Line Output Transformer

The LL1689 is available in 2 versions to suit the circuit topology. (The air-gap is adjusted during manufacture to suit)

• Push-pull
• 18mA 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)
• Nanocrystalline (NC)

Also, there is an option to have a Faraday Sheild fitted to your transformer to reduce the noise floor.

• Without a Faraday Sheild
• With a Faraday Shield (S)

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

• Copper
• Silver (Ag)
