What is a Lundahl transformer?
Lundahl transformers are very high-quality audio transformers from Sweden and are used for galvanic isolation, balancing and impedance matching. Typical applications include output transformers for tube amplifiers, either single-ended or push-pull, MC step-up transformers for high-quality phono systems, line input and output transformers, balanced or unbalanced, and interstage transformers.
Depending on the circuit, Lundahl transformers are used to improve sonic characteristics, reduce hum and, of course, for matching.
