□ Innovative Cooling System to maximize power device performance:

The greatest feature of VA-40 rebirth is its elaborate structure, in which a large heat sink with MOSFETs attached is placed at the top, and the main board is supported by rods facing upside down underneath it. Single push-pull drives have the advantage of focused reproducibility, which is difficult to achieve with parallel push-pull, but the minimum quantity of four power devices can reach quite high temperatures. VA-40 rebirth has MOSFETs firmly fixed to a large, squeal-free heat sink with excellent vibration damping properties, and heat is efficiently dissipated through the vents of the lid. MOSFETs that operate under optimum temperature control can continue to show their capabilities without thermal degradation of their characteristics. The main board mounted on the bottom of the heatsink is not affected by the heat and maintains its performance, further improving the durability of the components
