LL3727: Lundahl Output Transformer

The LL3727 is an output transformer designed for single-ended tube amplifiers, specifically suitable for KT88 and similar electron tubes. This is used in the Elekit TU-8850VK stereo kit. The transformer is composed of two coils, each consisting of three sections. The windings are arranged to minimise destructive capacitive coupling between primaries and secondaries. The C core is a high-quality grain-oriented silicon steel C-core from Lundahl`s production. A 50% UL tap is available.

The LL3727 is only available in one version.

  • 90mA Single-ended with a 50% Ultra linear taps

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: 4R or 8R

Overall dimensions including pins - 115mm x 85mm x 77mm
