Nanocrystalline C-cores
Finally our new nanocrystalline C-cores have arrived! We have been looking at nanocrystalline C-cores before, but we have not been satisfied with their quality. These kids looks so much better!!! Initially we plan to develop an interstage and a line output transformer using these C-cores.

PCB
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 [...]
Rubber Vibration Isolators
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, [...]

Mains transformers
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 [...]

New transformer
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 [...]
