Here is a presentation of our 1660. We also like to take this opportunity to wish you a Happy Eastern! 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 [...]
Finally, we have updated our online product presentations with individual product pictures. For instance, check out the general purpose transformers. All our different products can be found under each category at the product page, or click here to go directly to the page.
The LL1691 and LL1691B are our most popular SE transformers for high impedance high power tubes. However, so far these transformers have only been available with an 8 ohms secondary. With a minor modification we have now been able to extend the above range with: LL1691D (10k : 4, 16 ohms) and LL1691E (20k : [...]
We have created a library with photos and graphic material for downloading from our homepage. You can find it under "about us" or click here to go direct to the library. The library will continually be filled with more material.
