LL2735F: Lundahl Output Transformer

The LL2735F is the 4R / 16R secondary impedance version of the LL2735B. The transformer is designed for high rp tubes such as 10Y, 801A and EML20B in single-end applications. The transformer is a dual coil transformer where coils are wound using our high internal isolation technique with isolation foil between each layer of copper wire. Each coil consists of one primary and two secondary sections. The isolation between primary and secondary sections gradually increases closer to the tube anode connection to minimize capacitive energy storage. The core is a silicon-iron audio C-core of Lundahl production.

The LL2735F is only available in one version.

• 30mA Single-ended

There are further 2 versions depending on what C-core material you require.

• Silicon-iron
• Amorphous-iron (AM)

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

• 16K: 4R or 16R

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