PA-1 is pure mono block power amplifier with 230W output power. It is good on the high fidelity on music performance and with fashion enclosure design. Its sound has high solution, wide sound field, balanced feeling and exactly focus.
PA-1 adopts current negative feedback amplifying circuit. The current amplifying part is three grades Darlington circuit, and the output transistors are 6 pairs of SANKEN 2SA1295/2SC3264 power transistors, whose peak current is 102A. There are two pieces of 300W toroidal transformers. The total capacitance of the filter electrolytic capacitance for main power is 100000uF/80V.
