This amplifier was obtained from an Electronics Now from the 90s. The circuit has a dual 26V power supply. Power integrated circuits must be equipped with good heat sinks.
We found this circuit in a 1998 documentation. It is based entirely on relays that must have...
This traditional complementary symmetry circuit provides 20 W of rms power at a load of 8 ohms...
Assembled with SMD components this circuit can be very small. The range is a few tens of meters. We...
