Double C nickel-based amorphous C-type output transformer 20K: 600 ohms: for ECC88, 12AU7, 6N8P, 6N9P, 6N1 and other electronic tubes in parallel to promote the output. It is used for transformer output circuit, which can directly drive the rear stage or earphone.

The iron core is an imported nickel-based amorphous C-type iron core, a second-hand iron core, the iron core is very thin and extremely brittle. If you accidentally install the iron core, it will pierce your hand.

The C-type amorphous iron core is a high-end electronic tube-end output transformer iron core, which is very brittle and cannot be beaten with force. The core is also very thin, similar to natural insulating mica ore, which can be stripped layer by layer.

Selecting imported second-hand amorphous alloy sheets to wind the output transformer is the secret and basis for good results. The coiled output transformer has high and elegant high frequency, sweet intermediate frequency, stable low frequency, and has a better charm than many high-priced silicon steel chips, making the sound soft and durable, and the high and low frequency extension is wider, giving full play to the unique musical characteristics of the tube.

The use of imported second-hand amorphous alloy materials to wind, reasonable design, and complex process winding methods are the secrets and guarantees for the good effect of this transformer. The transformer is wound by 2C amorphous iron core and wire-wrapped skeleton epoxy board material. 8 clip 6 winding method, vacuum dipping and CNC drying, no counter-offer! The price-performance ratio is my responsibility, and the effect is welcome to compare.

Input 20K two lines, output 600Ω three lines, single-ended or balanced input is possible.
