New push-pull output transformer!
With a new internal winding structure, we have managed to reach very good HF response in our new push-pull output transformer LL3723 (4.3k : 4,8 ohms).

LL2785C is a new tube amplifier output transformer, specifically designed for 300B applications. A new winding structure improves HF frequency response by minimizing destructive capacitive coupling in the transformer.
They're here! Nanocrystalline cores made for us! This means that we can now offer nanocrystalline core versions of our transformers LL1660, LL1667, LL1668, LL1671, LL1689, LL1692A, LL2745 and some more of the same size.
The data sheet for our new single-end output transformer LL3720 is now available.In the LL3720 we are using a new winding structure to minimize destructive capacitive coupling between primary and secondary windings.This results in an improved high-frequency response. Lundahl Transformers LL3720
We are developing a new output transformer, LL3720 (6k : 8 ohms) specifically for single end application.By applying some tricks when winding the coils, the capacitive coupling between primary and secondary sections are minimized, which results in a better high frequency response. The transformer is suitable for triodes with plate resistance between 1 and 2 k, [...]
You haven't missed our “Lundahl Transformers inside” labels, have you? How to get them?The labels can be requested with your order of transformers from us or our distributors, free of charge. If you want to get the label only, to put on existing equipment, postage cost is €2,50 for a pair. Make a payment with [...]
Our new mains transformer LL2792 is specifically designed for 300B tube amplifiers. The 350V secondaries can be used with full wave or with bridge rectifiers. All secondaries can be used individually except for the 2 x 75V windings. These should either be used in series or in parallel, not individually.
Our newcomer, LL1968 is a small size transformer with flying leads designed for microphone design or repair/upgrade. Turns ratio is 2:1, and a center tap is available on the "1" side for phantom power.
Our first transformer with nanocrystalline core, LL2793NC, is now available for purchase. It is a line output transformer, similar to the LL1680 or LL1689 (9+9 : 1+1+1+1), but with turns ratio 4+4 : 1+1+1+1. Nanocrystalline is so far the most exclusive core option in our transformer range. From Rumen Artarski at Thrax Audio, one of our [...]
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.
