Lundahl LL1580 Audio transformer
Description
The LL1580 is designed for splitting signals in application where large and noisy ground differences appear, but where external magnetic fields are under control. By careful design, including double electrostatic shields, the capacative coupling between the different parts of the transformer is kept to a minimum.
