LL2755: Lundahl Output Transformer

The LL2755 is available in 2 versions. (The air-gap is adjusted during manufacture to suit)

• Push-Pull
• 60mA 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)

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

Primary impedance: Secondary impedance

• 5K: 5R or 8R
