Double C nickel-based amorphous C-type output transformer 7K: 4 Euro 8 Euro: specially built for 6V6 6P6P 6P14 6P1 6P15 6BQ5 6005 6AQ5 and other electronic tube machines. The iron core is an imported nickel-based amorphous C-shaped iron core. The second-hand iron core is very thin and extremely brittle. When you install the iron core, you will accidentally pierce your hands.
C-type amorphous iron core is the core of high-end electron tube output transformer, the core is very brittle and can not be beat with force. The core is also very thin, similar to natural insulating mica ore, which can be stripped layer by layer.
The use of imported second-hand amorphous alloy sheet winding output transformer is a good cheats and basis. The winding output transformer has high-frequency elegant, sweet mid-frequency, stable low-frequency, better charm than a lot of high-priced silicon steel sheet cattle, making the sound soft and listenable, the high and low frequencies extend wider, and give full play to the unique music characteristics of the electronic tube.
The use of imported second-hand amorphous alloy material winding, reasonable design, complex process winding method is the secret and guarantee of the good effect of this transformer. The transformer is wound by 2C amorphous iron core, wire package skeleton epoxy board material, The six-clamp four-winding method is equipped with iron core vacuum varnishing and CNC drying. The effects are welcome to compare.
Shira parameter: The data will be different due to different measuring instruments.
The primary inductance is about 17H-22H. The DC resistance is about 240Ω, the secondary DC resistance is about 0.5Ω (4Ω), 0.8Ω (8Ω), the leakage inductance is about 15--18mH, the distributed capacitance is about 1.5nF, and the six-clamp four-winding method.
Frequency response: 18Hz ~ 27KHz -3db. 24Hz ~ 20KHz -1.8db. The volume is 90mmX65mmX75mm. The weight is about 1.66 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 high-end transformers, with an output power of about 6.5W and an operating current of about 70mA.
Evaluation: high-frequency elegant, sweet mid-range, calm low-frequency, better charm than many high-priced cattle!
