LL1527, one of our oldest audio transformer designs, is still in production and still very popular. Many sound engineers have a couple of LL1527 laying around to be used when problem arises. Frequently engineers tell us: “I had some hum in my system, but as soon as I installed one of your magic LL1527, the [...]
All animals are equal, but some animals are more equal than others (From Animal Farm by George Orwell) There are many XLR-XLR in-line isolation units on the market. They pretty much look the same, so what is the difference, and why should you pay substantially more for a Lundahl unit compared to units of other [...]

Our MC step-up family is growing! Let us introduce the three newest members: LL1961, an amorphous core low turns ratio MC SUT designed for solid state applications. LL1963, the mu metal lamination version of the 1961. LL1971, is bridging the turns ratio gap between the well-established LL1931 and LL1941.

Our ambition was to make some of the best step-up transformers on the market available for vinyl audiophiles at an affordable price. [...]
Here is a presentation of our 1660. We also like to take this opportunity to wish you a Happy Easter! LL1660 was designed by Lars Lundahl around 1996. It is the first in our new generation of six-sectioned interstage transformers, and it has become very successful. Due to a flexible winding structure (2.25 + 2.25 [...]
When winding audio C-cores, the newly wound core-to-be needs to be press shaped for better form and for releasing it from its mandrel. We finally decided that our old, pneumatic press was not fully up to the job so we built a new, hydraulic unit. Check out the video at our Facebook page!
Some years ago our range of MC step-up transformers more or less consisted of one transformer, the LL9206. It is probably one of the highest performance-per-dollar MC SUTs on the market, having been used by a number of respected audiophile brands. However, the LL9206 had characteristics that made it usable for a wide range of [...]
