400W and 800W Power Amplifier Circuit

At this post is share about power amplifier circuit, I share two schematic circuit power amplifier, which is a power amplifier with output power of 400W and 800W. Both are the same have 8 Ohm output load, but with different components and the power supply voltage is different. Let's look at a circuit schematic below.

In the circuit 400W power amplifier uses transistors on the base strengthening. Similarly, a 800W power amplifier circuit. However, a highly significant difference was a series of buffer transistor, driver, and the finals.

For a 400W power amplifier circuit using the transistor below.
Buffer Stage : A970 2X and TIP31 1X
Driver Stage : TIP31 and TIP32  1X
Final Stage : 2SC2922 and 2SA1216 1X

While for the 800W power amplifier circuit using the transistor below.
Buffer Stage : A970 5X , C2240 2X , BD140 1X , BD139 1X ,
Driver Stage : TIP31 and TIP32 1X
Final Stage : 2SC5200 and 2SA1943 10X

Min and Max Power Supply are power amplifier :
400W Power Amplifier Circuit : 25V - 45V DC Ct
800W Power Amplifier Circuit : 35 - 45V DC Ct

Both the circuit above is a series of monolithic power amplifier, so you need 2x the circuit 2x component to create a stereo power amplifier circuit.  Transformer recommended that is 5 to 10 Ampere.

If you assembling circuit above properly and correctly, Power amplifier will be used and work optimally with a quality sound output.

Electronic Circuit is a good site for hobbyist also who would like to try DIY because it shared good circuits. If you have a personalized circuit requirement you may feel free to request it through the comment box or contact me.
