LL1691
Big Size Tube Amplifier Output Transformer
The LL1691 is a dual coil C-core tube amplifier output transformer for 9k: 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.
