The LL1545A is an excellent sounding line input transformer used in both pro audio and audiophile applications. However, one of the frequent critics regarding the LL1545A is the pinout.

This year we have extended our range of chokes and inductors, and therefore restructured our web page where the chokes are presented. The chokes are separated into four different categories based on operating current. As there is no fundamental difference between chokes intended for power supplies applications or for anode choke applications, anode chokes can [...]

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.
