Signal amplification for Russia 12AT7, JJ 12AU7, and Russia 6SN7
Two Russian KT170 are pushed and pulled for amplification, with a magnificent and imposing sound
Carefully crafted panels that resemble art
Aviation aluminum material, through multiple processes such as wire drawing, silver white fine sand, and high gloss cutting, combined with curved lines to improve texture
Using silver white fine sand aluminum plates on both sides to increase the weight of the body and effectively suppress noise
Highly matched balanced input
Horn output terminal setting: 4 Ω, 8 Ω, 16 Ω output selection
Better matching of speakers with different impedances to enhance the sound effect of the speakers
Customized horn terminal for Line Magnetic Logo, insulated with nylon+glass fiber, POM insulation gasket, and overall contact part made of copper+embedded high-purity carbon brazing
Adopting AMRG gold foot carbon film resistor imported from Japan
German Mundorf, American MIT capacitors
Further improve sound quality
Nissan Z11 has excellent quality
Both the power transformer and output transformer are made of Japanese steel Z11 EI silicon steel sheet
The output transformer adopts a manufacturing method of 4 layers and 3 layers, which allows for good extension and diving of high and low frequencies
