Hi, I'm a noob, just trying to get along with the electronics, and I put together a pretty nice amp from an old Grundig TV board, with two TDA2040 35W transistors. But I tried to connect some other circuit from the 12V power source, and I caused a short circuit between the plus and minus, so the amp stopped sounding right away. Then after a few minutes when I tried it again it was seemingly sounding back. Only that the right speaker is louder than the left speaker now. It could be damaged, the left TDA2040? I don't recall to observe this obvious difference in the sound between the left and the right before that short circuit. In the book it says TDA2040s have a built in short circuit protection. Anyone worked with these type of transistors before?
I also wondered myself if I would need to change the TDA2040, couldn't I better change them both with two TDA2050, on the same circuit board? Is it needing some other modifications in other components? On the paper the two transistors have the same pins, and other people around the internet said it's doable, it will only draw more power.
Thanks for any suggestions. Cheers.

 

The Tda2020 /50 series are an audio amplifier, their pinout is the same, they just have different wattages and current draw.
No modifications are needed just gain settings.
