Tube amplifier output transformer LL1663 5k : 8 ohms
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.
Turns ratio 12+12 : 1 or (4+8)+(4+8) : 1
Weight: 1.35 kg
Static resistance of each primary: 102 Ohm
Static resistance of secondary: 0.4 Ohm
Isolation between windings / between windings and core: 4 kV / 2 kV
Max DC current through any primary winding: 160mA
