The circuit is dependable and steady, and it uses the TDA7293 is a monolithic integrated circuit in a Multiwatt15 package designed for audio class AB amplifier usage in Hi-Fi field applications. It can deliver the most power into both 4- and 8-loads because of its wide voltage range and strong output current capabilities. The built-in is simplified by the built-in muting feature with turn-on delay, which eliminates on-off switching sounds. High output power may be provided to loads with very low impedance, reducing the system's heat dissipation. For massive electrolysis, the filter utilizes a voltage of 50V and a capacity of 2200uf, with a supply voltage of 12-36V.
