Check the number of transformers installed on the machine: Genuine tube amplifiers require three transformers (one large power transformer and two smaller output transformers). Our product's power transformer (1055001) is made of high-quality black annealed silicon steel sheets and oxygen-free copper wire, delivering a full 200W of power. It remains cool and vibration-free, and comes with a side cover. The output transformer (864201-3) is wound using a 3+2 winding method, with the core made of Japanese Z11 silicon steel sheets that are 0.35mm thick. The use of Z11 sheets results in higher magnetic permeability, producing deeper bass. The performance is significantly better than that of domestic H14 and H18 silicon steel sheets. Since transformers account for the majority of the machine's cost, this aspect deserves special emphasis.
