Power amplifier 450W with sanken

Circuit of power amplifiers with power output of 450 watts mono with transistor booster sanken 2SC2922 and 2SA1216 , amplifiers are also frequently used in the amplifier a high-power amplifier, which used in an event, in the field and the placed closed. Because this amplifier suitable for the woofer, fullrange speaker, and can also be fixed for the subwoofer speaker. To further strengthen and maximize the amplifier ,its power supply circuit also must be accurate, for electrolytic capacitors in power supply ,voltage capacitors use 80V or more, and a capcity 20000uF upwards, so when the bass amplifier is high , the voltage is not lot of experience dropping. Diode bridge use a minimum of 35A, or adjust the current input voltage. If the power supply has fulfilled the desire, the supply to the power amplifier.

In the buffer circuit uses PNP transistor A1266 / A564 / A733 /A1015 / A798 and NPN with MJE340.To the driver circuit using PNP transistor MJE350 and MJE350. For the final amplifier circuit use two set 2SC2922 and 2SA1216. Use a quality sanken transistor to maximize quality sound output.

Below is the amplifier and finshed PCB layout.

If the track pcb does not look, you can download this series in the form of fort board, use the eagle cadsoft application to open it, but its components are not ordered , to their own satisfaction you can design it with your whishes.

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.


it cannot deliver 450 watt output if your transformer looks like 2 amps big only

oohhh... what happen to the trans.. very cute.. surely cannot support the circuit....

transformator brand it's ERA transformer , but the transformer is packaging on box.

pls allow and feature parts and pcb.

what doyou talking about parts or pcb sell?

Please, could share the Eagle file again ? at moment its 404 ! Thanks.

sorry i dont have the eagle file , because this post was publised on year 2011. File is lost. Sorry sir

never 2 sanken deliver 450 watts in AB CLASS MAYBE 225 WATTS MONO....

thaks for comment,

hello marcellus, yeah its maybe 450 Watt because you can calculate with other factor. Such as input voltage, buffer and driver circuit.
