1pair Amorphous iron core 2.5K and 3.5K single-ended output transformer 2A3 or 300B amplifier with 4 ohm 8 ohm 16 ohm
Amorphous iron core 2.5K and 3.5K single-ended output transformer 2A3 or 300B amplifier with 4 ohms, 8 ohms and 16 ohms, can also be used for other tube circuits.
The magnetic permeability of the amorphous core is between the Z11 core and the permalloy.
This C-type nickel-based amorphous core is very thin and brittle, similar to natural insulating mica ore can be peeled off layer by layer. 1000W high-power nickel-based amorphous iron core is rare and rare, used in the output transformer of the amplifier, good horse with good saddle, carbon in the snow, icing on the cake.
The secondary output of the transformer is 4 ohm, 8 ohm, 16 ohm output, matching various impedance speakers.
Imported oxygen-free copper enameled wire is carefully wound, without border coil, each layer is insulated with pure wood pulp insulation paper, and there is no skeleton layered segment winding process to reduce leakage inductance and distributed capacitance to a lower level.
Transformer outer dimensions: width 98mm height 82mm thickness 65mm, weight about 3.3kg / pair
Measured basic parameters:
Primary inductance approx.: 16H
Primary copper resistance; 140 ohms
Secondary 8 ohm copper resistance; 0.6 ohms
Distributed capacitance; 12N
Leakage inductance; 9mH
Frequency response: 15Hz ~ 49KHz -0.6db.
The data will vary depending on the measuring instrument and is for reference only.
This output cow sounds relaxed and natural. The treble is transparent, bright and clear. The midrange is warm and feminine, the bass is full and strong, generous and powerful, and the music is very strong. The sound of the air is very good.
