Lepy LP-2020A Power Supply

The Lepy LP-2020A power supply is usually a mains power adapter capable of producing 12 V DC, and up to 3 A current. This particular one is switched-mode, which comes with the amplifier should you chose the bundled option. The specification states that it also operates from a +12 V DC battery. In any case, the available current is an important factor to consider. When I opened this amplifier I noticed one small electrolytic capacitor across the power rails and therefore there is limited smoothing available to the circuitry. Consequently, when choosing a power supply, make sure that it has sufficient built-in reserve.
