LL2785C: Lundahl Output Transformer

The LL2785C is available in 3 versions. (The air-gap is adjusted during manufacture to suit)

• 60mA Single-ended
• 70mA Single-ended
• 90mA 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 2 versions depending on what C-core material you require.

• Silicon-iron
• Amorphous-iron (AM)

Depending on how the winding sections of the transformers are wired together via the exposed solder pins, the constructor can adjust the following primary and secondary impedances.

Primary impedance: Secondary impedance

• 3K: 5R or 8R
