LL1585 High Level Audio Output Transformer

LL1585 is a high level audio line output transformer for balanced or unbalanced drive. The transformer is built
from two three-section coils, with primaries and secondaries separated by electrostatic shields, and a audio Ccore of our own production. The transformer is housed in a mu-metal housing.
The LL1585 is (as all output transformers) ideally used with mixed feedback drive circuits. (See separate paper
for mixed feedback design principles).
