dual C nickel-based amorphous C-type output transformer 2.5K: 4Ω8Ω16Ω, epoxy board skeleton: specially built for 6Y6, 2A3, 6C19 and other electronic tube machines. The core is a British nickel-based amorphous C-type second-hand core. The core is very thin and very brittle. It can be stripped layer by layer similar to natural insulating mica ore.
C-type amorphous iron core is the core of high-end electron tube output transformer. The iron core is very brittle and can not be struck by force, collide and drop by force.
The use of imported amorphous alloy materials to wind the output transformer is a good cheats and foundation. The permeability of the C-type amorphous iron core is much higher than that of the iron core. The winding output transformer has a high-frequency elegant, sweet mid-frequency, low-frequency calmness, and charm is better than many high-priced silicon steel cattle, making the sound soft and audible. Give full play to the unique music characteristics of the tube.
In addition: C-type amorphous iron core has a large window area, which can accommodate a thicker wire diameter, reduce copper resistance loss, and improve the effect.
Reasonable design and complicated process winding method are the secrets and guarantees of the good effect of this transformer. The wire package skeleton epoxy board material, six clips and four winding methods, and the iron core vacuum dipping varnish are controlled by CNC drying. ! The effect is welcome to compare.
Measured parameters: The data will be different due to different measuring instruments.
The primary inductance is about 30H. The DC resistance is about 279Ω, the secondary DC resistance is about 2.6Ω (16Ω), six clips and four windings.
Frequency response: 15Hz ~ 27KHz -3db. 20Hz ~ 20KHz -1.8db.
The power is about 6.5W, and the working current is about 70mA.
The volume is 86mmX65mmX75mm. The weight is about 1.68 kg / pair.
The entire frequency band of the transformer is very balanced, the low frequency is powerful, the intermediate frequency density is large, and the high frequency is transparent and delicate. It is one of the top-grade transformers.
Evaluation: high-frequency elegant, sweet mid-range, calm low-frequency, good taste.
