IWISTAO 300B Output Transformer C Type Single-ended British Amorphous 8C Advanced Core Pr 3.5K

300B Output Transformer C Type Single-ended British Amorphous 8C Advanced Core Pr 3.5K Se 0-4-8 ohms

This 300B single-ended output transformer uses British amorphous high-grade C-type iron core that has a unique advantage, especially when he static operating point is 80ma or below , it can give full play to the advantages of the output transformer. After actual measurement and listening, the voice is very vivid, clear, low-frequency tension is very balanced in three bands, excellent permeability and atmosphere feeling

Using high-quality enameled wire, lamination process, CNC drying, vacuum impregnation, well-designed 8C structure, to design to a perfect coefficient.


It is a better choice to tube amplifier audiophiles. Also, there is a matched power transformer.

IWISTAO Passive Preamplifier Kit Unbalanced to Balanced/RCA to XLR/Signal Input Transformer

When you use your mobile phone or computer to listen to music, you will find that the sound is small, the details are small, and the dynamic is thin, their sound quality aren’t full and pleasant like as CD player, decoder. This is because the output value of mobile phone and computer is 0.2-0.5V audio voltage only, while the existing power amplifier is generally designed with an input voltage of 0.75-1.2V. This intermediate voltage difference requires a 2x amplification boost value. Now the 1:2 signal boosting transformer solves this disadvantage.



1:2 signal boosting transformer, balance transformer, and inverter transformer, that is a passive boosting transformer developed to compensate for low signal output of computers and mobile audio sources in the existing market. Make the ordinary sound source close to the effect of CD player signal one. And, if CD player connected the signal boosting transformer to power amplifier, its sound will be even more powerful. After the audio signal pass the boosting transformer and amplify, it will output a stable impedance, it will lead to its signal transmission is fidelity, and its sound field positioning is better!
