The LL1663 is a four-sectioned dual coil C-core tube amplifier output transformer for 5 k: 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.
Weight: 1.35 kg
Static resistance of each primary: 102 W
Static resistance of secondary: 0.4 W
Isolation between windings / between windings and core: 4 kV / 2 kV
Max DC current through any primary winding: 160mA
