LL1664
Tube Amplifier Output Transformer 3k : 8 ohms
The LL1664 is a four-sectioned dual coil C-core tube amplifier output transformer for 3k: 8 ohms impedance ratio available in PP and SE versions.
The coil is wound using our high internal isolation technique with isolation foil between each copper layer. The core is an audio C-core of our own production.
