Audio Output Transformer
LL1517
LL1517 is an audio 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 C-core of our own
production. The transformer is housed in a mu-metal housing.
The LL1517 has sufficient low copper resistance to meet broadcast specifications in a conventional drive
configuration, but is (as all output transformers) ideally used with mixed feedback drive circuits. (See separate
paper for mixed feedback design principles).
