1400W audio power amplifier
This is an amplifier circuit that has a high output power is 1400W mono, the audio amplifier circuit is very suitable when used in a large room, using a woofer speaker, and fullrange. To sound out very nice, loud sound and almost no noise.
The amplifier using a transistor amplifier-quality, and for the final amplifier transistors can use a variety of high-power transistors. Minimum required supply voltage + / - 25V and a maximum of up to + /-90V.
For transistor 11 to 17 should use a heatsink, because if the maximum working range of the transistor heat and should be to install the heatsink. But do not forget also to the final amplifier transistor circuit should also be given a heatsink such as transistors 18 to 21.
