LA4440 is a two channel audio power amplifier IC with inbuilt in dual channels enables it for stereo and bridge amplifier applications. In dual mode it gives 6 W per channel and in bridge mode 19 W output.
Good stability and sufficient amplification in Transistor based circuits depends on the proper selection of components and their layout. Gain of the transistor used as well as the current and voltage through it are the most important aspect in the working of a transistor amplifier. Here explains the design parameters of an one transistor amplifier circuit.
Now you can protect your HiFi amplifier from damage due to excess heat. This circuit will cut off the power to the amplifier board at the moment it senses a high temperature. It automatically connects power when the temperature returns to normal. The circuit uses an NTC Thermister as heat sensor and it also has audible warning and reset provisions

A line amplifier is a circuit which is good to have around to adjust a the line or raise the level. This may be necessary during a recording or in a broadcasting system. In addition with some of these amplifiers can be built a mixer line.
