Pair of Single Ended Output Transformer for Headphone amplifiers ,10W Designed for EL84-6BQ5-ECL82-ECL83 in triode mode or tubes with similar impedance, built in a massive core for lowish distortion in low frequencies.
TECHNICAL FEATURES:
Primary Impedance: 5k
Secondary Impedance: 32/75/150/300 Ω
Primary Inductance Lp=35H @17Vrms/50hz
Airgap set for : 36mA
Primary Dc resistance: 223 Ohm
Max Dc current :150mA
Maximum output power : 10W
Frequency Response: 20Hz-49Khz -3dB at 5W
Output power with Idc=36mA If the transformers are used with lower value of Idc then the low frequency response is even better.
Core material: high quality annealed M6 silicon steel (19Kilogauss)
Lamination thickness :0.35mm
Core size: EI75/40
Dimensions :75mmx63mmx83mm
Weight:1.45Kgr per transformer
Winding Wire: Double coated Grade 2 enameled copper wire Wound with Precision , Multi section winding, for reduced leakage inductance and high dielectric strength.
Secondaries are wound in bifilar method to ensure perfect load match and same bandwidth for all loads between 32/150 /300/600Ω.
The user can rearrange the secondary taps for different load value following the enclosed connection diagram.
Mounting: open frame clamps suitable for vertical or horizontal placement.
