Power Amplifier for Horn Speaker

Power Amplifier TOA

Power Amplifier for using on Horn Speaker / Loudspeaker its can be make by this circuit below. On power amplifier circuit is using transistor D313.For driving transistor , its adding Trafo IT as a buffer combine with d313. Main output using Trafo OT (output) the trafo OT is drived by transistor 2n3055. This power amplifier you can using for Horn Speaker with 100W or higher Wattage . We deliver 3 image about this amplifier that describe :

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.


Is there any further information on the 2n3055 siren/horn speaker amplifier; such as transformer types used, circuit board dimensions, and possible construction hints? I plan on building two for stereo. Anything would be deeply appreciated! Christopher Chapman; Kingston, Georgia; U.S.A.

Hello, what is the trafo type used

Hi Sir what is rating input output tranformer?

For input trafor IT426 and output OT426

inadequate description . With 12 V DC power supply this
amplifier will produce 1 - 2 watts ??
