Tube 10K: 32 ohms (8 ohms + 8 ohms) single-ended output transformer, two-purpose speaker and earphone amplifier, suitable for 6P1, 6P14, 6P15, 6N1 parallel, 12AU7 parallel, 6N11 and other electronic tubes.
This single-ended output transformer has a secondary 8 ohm dual winding, which is used in parallel for speaker speakers and 32 ohms in series for headphone amplification.
High-quality EI 48 Z11 iron core winding, iron core size: 48mm×40mm×stack thickness 24mm, tongue width 16mm, thickness of each piece is only 0.35mm, high magnetic flux (18000 to 19000 Gauss). Riding clip type iron hoop fixed.
Primary high-quality oxygen-free copper enameled wire winding, nylon skeleton, three-fold two-winding process, reduce leakage inductance and distributed capacitance, and improve quality.
The input and output wires of the transformer are made of imported German LEONI high-purity copper wire, the outer diameter of the wire is 1.5mm, the inner copper core diameter is 2X1mm square, the wire is soft, and the purity is 5N-6N, which is equivalent to the level of single crystal copper. The pure copper wire is bright without electroplating. It has good electrical conductivity and is very easy to tin.
The winding method of the transformer adopts the sandwich winding method to reduce the leakage inductance and distributed capacitance and expand the frequency response. Transformer outer dimensions: length 50mmx width 45mm height 42mm. Distance between left and right fixed center holes: 62MM
Actual measurement: The primary inductance is about 19, and the copper resistance is about 800 ohms. The secondary 8 ohm inductance is about 11 millihens, the copper resistance is about 2.4 ohms, and the weight is about 0.7Kg/pair.
Affirmation: Due to different test conditions and equipment, different production batches, the measured inductance and resistance values will be different, which is different from the advertisement.
