Wide frequency response double C amorphous 150Ω+150Ω: 12.5K+12.5K single-ended balanced step-up transformer, the primary series and the secondary series become 600Ω:50K, and the input transformer is used for the input and output circuit. 15HZ～25KHZ -0.5DB wide frequency response signal transformer.

The transformer can also be reversed to use 50K:600Ω for step-down use.

The input transformer for the tube pre-amplifier, the input 600 ohm:50K transformer, the voltage ratio is 1:9.128. That is to say, 600 ohms input 1V signal voltage, the output voltage of 50K winding is 9.128V, the signal is improved and amplified by nearly 10 times. The transformer wire wraps the iron core through the AC audio signal. You can also order a DC signal transformer, just take a photo and leave a message.

The transformer inputs 4 wires and outputs 4 wires. The primary and secondary layered winding of the transformer is to balance the input and output in two groups, instead of the conventional two-wire parallel winding method, it adopts a more special process, with the same number of turns, the same wire diameter, the same copper resistance, and the same internal resistance. The voltage is the same, the current is the same, the positive and negative voltage amplitudes are the same, a completely balanced signal transformer! It can be used as a passive front stage, single-ended to single-ended, single-ended to balanced, balanced to balanced, and balanced to single-ended.

This transformer is specially designed and manufactured for signal coupling and passive pre-stage use. It has a good isolation and polishing effect, which can quickly change the tone, eliminate the digital flavor, and enrich the analogy charm.

The permeability of the amorphous iron core is higher than that of the iron core and lower than that of the permalloy (nickel alloy) iron core. Transformer wire package skeleton epoxy board material, 8-fold 6-winding method, cost-effectiveness is my responsibility, and the effect is welcome to compare. The volume is 90mmX65mmX75mm. The weight is about 1.9 kg/pair.

Measured parameters: The data will be different due to different measuring instruments.

Measured parameters:

Primary DC resistance: 25 ohm + 25 ohm

Secondary DC resistance: 225 ohm + 225 ohm

Primary inductance: about 338mH + 338mH about 100HZ measurement

Secondary inductance: about 22.6H + about 22.6H 100HZ measurement

Leakage inductance: about 12.5mH, measured at 1000hz

Distributed capacitance: about 450p 20KHZ measured

Over signal current 60mA

Withstand voltage: 1000V

Frequency response: 15HZ～25KHZ -0.5DB, 35K-1DB 43KHZ-2DB

It is not easy to achieve this frequency response with nearly 10 times boost, and those who know how to do it will naturally know.

The resistance and inductance parameters are subject to the VICTOR victory 4090B desktop digital precision bridge test.

Affirmation: Due to the continuous improvement of the product, some parameters will be different from the data provided above, so please be aware that there will be no separate notice.
