Bridge connection of National LM388 power opamps provides 3.5 W to 8-ohm loudspeaker when using 12-V supply. With 6-V supply and 4-ohm load, maximum power is 1 W. Coupling capacitors are not re quired since output DC levels are within several tenths of a volt of each other.- Audio Hand-book, National Semiconductor, Santa Clara, CA, 1977, p 4-37-4-41.
