output TEA2025B and tda2822 have been replaced but continue heating the output. This handset used two left and right audio inputs and two outputs for smaller speakers plus a 15w 6 ohm speaker . I would like to replace every amplifier circuit using other components equivalent to the original circuit.
I have in my workshop the TDA2030 amplifier, can I make an equivalent circuit?
I wanted to set up another circuit using the 15w 6 ohms speaker, the two audio inputs (left and right) and two left and right outputs for speakers of 7.5cm or so in diameter .
12v AC power transformer and 15v DC voltage . Double volume potentiometer

Any sound amplifier produce heat.
