This small PCB is designed for some common applications using a few of our pin compatible transformer models. Typical applications would be galvanic isolation or balanced-to-unbalanced conversion. The PCB can be used in combination with a DIN housing, or can be screw mounted without any housing.In addition to the transformer, the board has two holes [...]
We have been working hard to eliminate mains transformer buzz generated in the windings and isolation material.But the core hum/vibration, caused by so called magnetostriction is not possible to totally eliminate in iron cores.A way to reduce the mechanical coupling between the transformer and any resonating chassis is to use vibration isolators.Therefore, for your convenience, [...]
Lundahl Transformers are first of all well known for audio signal transformers. But we also make a range of mains transformers, so far primarily for tube amplifier applications.Making quiet mains transformers is a challenge. Although we are proud of how quiet our mains transformers have become today, we continue to improve our manufacturing process and [...]
Tomorrow it´s Midsummers Eve, the most celebrated day in Sweden.This means that our factory will be closed, as we are busy celebrating this traditional feast!!!

Our summer holiday shutdown this year will be between July 6 and August 2. We wish you all a pleasant summer!
A new star is born!LL9226XL, the newest member of our MC SUT family.Despite the young age, the LL9226XL is a big sister to the LL9206 and the LL9226. The LL9226XL is of course very similar to the LL9226, with the same winding structure and the samt pinout, but the amorphous cobalt strip core size has [...]
Here is a Cheaptubeaudio review of the Elekit TU-8800 amplifier (VK Audio upgrade version) we cannot resist to share.In particular we like sentences like: "... even without much run-in, the Lundahl Transformers are a significant Upgrade!" and "They [Lundahl transformers]... elevates a very good product to an outstanding one." Thank you, Doctorjohn and thank you, [...]
