Note: When testing the machine, the output transformer must be connected to a speaker or a resistor as a load. The no-load test can easily burn the transformer. This kind of burn is not guaranteed.
15W amplifier single-ended output transformer EI86*42, there are a variety of input impedances to choose from, or customized according to requirements. Output impedance 0-4Ω-8Ω
Core size: tongue width 28.5MM*42MM stacked thickness
Winding method: 3 clips 2, vacuum dip paint, interlayer pad paper (not layered pad)
[The following data refers to the 4.2K input impedance, and the measured values of different impedances will be different. 】
Inductance: L> 35H@100HZ
Primary DC resistance <: 338Ω
Input impedance: 4.2K (any impedance value can be customized)
Output impedance: 0-4Ω-8Ω (any impedance value can be customized)
Core material: Z11 0.35MM thick insulation annealing sheet imported from Japan
Enameled wire material: 99.9% purity QZ-2 produced in Jiangmen, Guangdong, high temperature resistant two-layer patent leather oxygen-free copper, withstand voltage 1000V. The QZ-2 wire is much stronger than the QA-1 straight solder enameled wire. The QA wire is easy to break and short circuit. The advantage is that there is no need to remove the paint manually, saving labor costs, and can be directly soldered with a soldering iron.
Shielding method: vertical side shielding. If you need other installation methods, please communicate with Xiaoer 2 and support any installation method.
Weight: 2KG
Bandwidth: 30HZ-20KHZ (If the inductance is lower than ours and the low frequency of the bandwidth is lower than ours, Niu must be bragging)
Insulation method: dipping insulation paint
