Wide frequency response ultra-linear push-pull 8K/4 ohm 8 ohm output transformer, imitating the output transformer of Shanghai Meiduo electronic tube R10-2 amplifier. Mido R10-2 high-fidelity amplifier is a domestic classic HIFI amplifier. It was launched by Shanghai No. 3 Radio Factory in 1971. It was also the most representative high-fidelity tube amplifier at that time. The feature of the Mido R10-2 high-fidelity amplifier is that it spares no effort to build Hi-Fi on the output transformer. The output transformer and power transformer are about the same size, which is very rare in the previous tube audio. Not only is the material heavy, but also the workmanship is very sophisticated and the sound effect is extraordinary.

Z11 iron core winding measurement system, 76 pieces stacked 40mm thick, wide frequency response, large dynamics, and delicate sound! The effect is immediate! 12W8K push-pull amplifier output, suitable for 6P6P, 6V6, EL84, 6P14, 6BQ5 and other electronic tube push-pull amplifiers The iron core is inserted in pairs, the nylon wire wraps the skeleton, the high-quality oxygen-free copper enameled wire is wound, the use of 4 clips 3, positive and negative winding, layered winding, to minimize leakage inductance and distributed capacitance. When the parameters are measured at 1KHZ, the inductance of P1 and P2 is about 40H, the leakage inductance is about 60mH, and the distributed capacitance is 2300PF. The copper resistance of primary P1 and P2 is about 475 ohms, the copper resistance of secondary 4 ohms is about 0.5 ohms, and the copper resistance of 8 ohms is about 0.6 ohms. Total volume 80×69×70mm, weight 2.8Kg/pair
