The result is the correct part secured in the correct place for the lifetime of the amplifier. These, quite frankly, provide the best bang for the buck available today. Built tough with a heavy duty heatsink, robust unregulated power supply, oversized direct input power and speaker terminals. They also sound sweet thanks to the audiophile bi-polar output transistors.
