Choke coil for LP vinyl phono amplifier, low frequency choke coil for amorphous 4C iron core 42H 150mA 196Ω tube amplifier.
Imported second-hand amorphous 4C iron core, high-quality oxygen-free copper and copper enameled wire winding, Red Bull stand. The British nickel-based amorphous C-type core is very thin and brittle, and its magnetic permeability is much higher than the core and lower than permalloy.
The wire package does not use organic material nylon skeleton, adopts the original cardboard without borders, like the output transformer process of Shanghai Radio No.27 Factory, layer by layer of paper, layer by layer, layer by layer, all guaranteed by superb hand winding process The enameled wire does not fall, and the insulating paint penetrates the entire wire pack to protect the wire pack and the transformer core.
Can also be customized according to requirements.
The volume is 82mmX65mmX100mm. It weighs about 1.5 kg.
Approximate three-dimensional size: 85mm × 65mm × 75mm
Note: The inductance and resistance will be slightly different due to different test conditions and equipment. The inductance and resistance values measured in different production batches are slightly different and have certain dispersion. The above parameters are for reference only!
There is also an amorphous 4C core 150H 50mA 1096Ω low-frequency choke for tube amplifier, the volume is the same price.
