Lundahl Output transformer for headphone amplifiers, LL2765-30mA

Output transformer for headphone amplifiers LL2765

The LL2765 is a three sectioned, dual coil, C-core output transformer for headphone amplifier applications.
LL2765 is available in PP and SE versions.
The coil is wound using our standard high internal isolation technique with isolation foil between each copper
layer. The core is an audio C-core of our own production.
