Output transformers are required to have low distortion, high-level frequency characteristics, and various other factors such as efficiency, often referred to as "sound coming forward," including the goodness of S/N. In the HW series/H series, stable production methods have been achieved by using high-B cut cores (except for H-507S) and a unique multilayer sandwich winding structure. Detailed consideration has been given to materials and structural aspects, focusing on the pursuit of delicate and powerful sound. Additionally, in the case of single universal type transformers, a method of switching primary impedance at the primary side has been adopted to avoid bias in characteristics due to inappropriate inductance and various constants. Taps of P1-SG1 and P2-SG2 are provided according to impedance, prioritizing performance.
