Output transformers are required to have a low distortion rate, a high level of frequency characteristics, and performance that includes various factors such as efficiency, which is commonly referred to as of sound, to come forward and good S/N. In the HW series/H series, the stable production system was realized by the use of high B cut cores (Excluding H -507 S) and the unique multi-layer sandwich structure winding. In the universal type for single use, in order to avoid the deviation of the characteristics due to the proper inductance corresponding to the primary impedance and the incompatibility of various constants, the switching of the primary impedance is done by the orthodox method on the primary side, and the performance is focused by providing P1-SG1 and P2-SG2 taps for each impedance.
