Installers of audio systems are often not happy with naked transformers, as these require both soldering and solutions for mounting. In our DIN units you find three of our most popular general purpose transformers, prepared for installation using screw terminals and DIN rails. If no DIN rail is available the DIN unit can easily be [...]
The building style for our tube amplifier transformers is not particularly well suited for DIY amplifier builders. With high voltage present on the terminals of a naked transformer, the transformers should not be placed uncovered on top of the normal “pizza box” amplifier. So we commissioned a designer to make two sizes of enclosures for [...]
We welcome LL1952 to our transformer family. LL1952 is really one of a kind, it’s our first mic AND line input transformer combined. The LL1952 is an input transformer for mic and line input applications. The two separate primaries will provide mic step-up (1:4) or line direct (1:1) input. A transformer of this kind is [...]

The new small mains transformer LL2758 was designed in cooperation with Claus Byrith, for many years the head of the studio at the Royal Academy of Music in Aarhus. We have asked Claus to introduce the LL2758 transformer: ”The new mains transformer LL2758 is designed with the serious valve oriented audio enthusiast in mind. Its [...]
Many customers ask us for the difference in sound between our mu metal lamination transformers and our strip core amorphous transformers. We have forwarded the question to Kevin Carter at K&K Audio. Here are his impressions!
During the last year Lundahl Transformers have developed a new line of Single-End to Single-End 1:1 interstage transformers. When conventional design practice is applied to this type of transformers you easily get destructive capacitive coupling between the primary and secondary windings. This will reduce the HF bandwidth and increase HF ringing. After a more thorough [...]
A nice (we think!) preliminary review of the Cable Factory DI-Pro with our LL1530 transformer. DI boxes are used e.g. when you connect your electric guitar to a microphone preamp input. Thank you! We look forward to the final review when the unit is fully tested. Click here to read the review
