Balanced Transformer Output Pre-Amplifier using WE 205D


Well made audio transformers can provide perfect coupling in a hi fi system. Free from the “mechanical” sound of solid state and the deficiencies of output capacitors, they can make reproduction more vibrant and focussed.


The LA6tx uses four very special line level balanced input and output transformers, developed and manufactured in their laboratory over several years to give what we believe to be the finest sound.  Two are used for input and two for output. Enabling a true balanced signal path if required. This circuit also works equally well with single ended signals.

At the heart of the LA6tx is the WE designed 205D made by their colleagues at Psvane. Dating back to the early 1930s original versions now change hands for around $2,000 each. This venerable design has a unique “open frame” design and a sound quality which is like no other.


The LA6tx is designed for the very best transistor and valve power amplifiers where musical purity is required rather than starkness.

Summary:
A simple low gain pre-amplifier using transformers and the unique WE 205 valve where the emphasis is very much on the ultimate sound quality using transformers. Designed for the very finest systems where listening quality takes precedent.
