Amorphous Iron Core Amorphous Iron Core, Choke Coil for Tube Amplifier

Double-C Nickel-Based Amorphous Type-C Choke Coils: Specially built for tube machines. The iron core is a British nickel-based amorphous C-type iron core, a second-hand iron core, the iron core is very thin and extremely brittle. When installing the iron core, it can be accidentally pierced into the hand.

The C-type amorphous iron core is a high-grade tube-side output transformer choke coil core, which is very brittle and cannot be beaten hard. The iron 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 sheets to wind the output choke has a good effect, which can give full play to the unique musical characteristics of the electronic tube.

Imported disassembled amorphous C-type iron core, fixed with iron bracket and stainless steel hoop, suitable for choke coils for single-ended push-pull amplifiers such as 6P14/6P3P.

Epoxy resin insulation board skeleton wire package, oxygen-free copper enameled wire, vacuum dipping process to ensure that the insulating paint penetrates into each circle of enameled wire to protect the wire package and the iron core. The choke coil weighs about 1kg.

Three-dimensional approximate size: 85mm×65mm×75mm

The choke coil air gap, copper resistance, current, temperature rise, inductance, etc. are optimized.

Yes: 150mA 45-85H 430 Ohm

Yes: 200mA 8H 82 ohms

Yes: 350mA 5H 45 Ohm

Note: The inductance and resistance will vary slightly depending on the test conditions and equipment, and the inductance and resistance values measured by different production batches are slightly different, and have a certain discreteness. The parameters provided above are for reference only!

Supporting epoxy resin insulation board skeleton. Epoxy resin insulation board (commonly known as glass steel plate) transformer skeleton, the board thickness is 1mm, the assembled skeleton does not need any adhesive, and there are tenon and mortise everywhere, which is very strong and firm, and has excellent electrical performance. A skeleton consists of 4 epoxy resin insulating boards. The skeleton provides convenience for making transformers, high space utilization, high dielectric strength, and smaller dielectric constant. The direct benefit is that the same large iron core allows more turns or uses a thicker core The diameter of the enameled wire, the strength of the skeleton is incomparable with the plastic skeleton. Especially for all kinds of audio cows, the smaller dielectric constant can make the distributed capacitance between the wire package and the iron core smaller, bringing more transparent and delicate high frequency performance, which is more effective in the reproduction of antique audio cows. good performance.
