Imported high-power vacuum tube with magnificent momentum

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
