LL2785B: 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)

Windings are provided for an optional cathode feedback connection. 7% tapped.

The constructor can adjust the secondary impedances, depending on how the winding sections of the transformers are wired together via the exposed solder pins.

Primary impedance: Secondary impedance

• 3.4K: 5R or 8R

We currently have stock of the LL2785B 60mA, single-ended version.
