New single-end output transformer!

2022-11-16T10:51:34+01:00September 2nd, 2022|News, Products|

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

New output transformer

2022-11-16T10:51:35+01:00August 19th, 2022|News, Products|

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, [...]

LL2793NC

2022-11-16T10:51:40+01:00March 18th, 2021|News, Okategoriserade, Products|

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 [...]

PCB

2022-11-16T10:51:42+01:00October 29th, 2020|Products|

This small PCB is designed for some common applications using a few of our pin compatible transformer models. Typical applications would be galvanic isolation or balanced-to-unbalanced conversion. The PCB can be used in combination with a DIN housing, or can be screw mounted without any housing.In addition to the transformer, the board has two holes [...]
