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, [...]
