Ultra-LD Mk.2 200W Power Amplifier Module, Pt.2

摘要

Last month, we introduced our new Ultra-LD Mk.2 200W Amplifier module and described the circuit. This month, we give the assembly details and describe a suitable power supply. THIS NEW 200W audio amplifier module gives superlative performance - better than any of our previous class-AB amplifiers. That's been made possible by the use of On Semiconductor's new ThermalTrak power transistors, a circuit based largely on our high-performance class-A amplifier (published in 2007) and a new double-sided PC board with plated-through holes.
