hi guys... can anyone pleases help me as to what ic will match to replace the TD1514A so i can get much power? the TDA1514A gives off 50W... tnx guys...
Your question doesn't give us much to go on. However since the answer is there are no single chip amplifiers that give significantly more than 50W and none that are pin for pin compatible. You best bet unfortunately is probably to buy a bigger amplifier rather than try to modify the one you have.
To increase power you don't just need a higher power amplifier chip you will need a bigger power supply, higher voltage rated capacitors etc.
If you plan to design some thing from scratch then there are some amplifier modules that will provide significantly more power but I think the best chip amplifer is probably the LM3886 amplifiers at max power will provide 68W into 4R at 0.1% distortion on +/- 28V rails. But to be honest this increase in power is unlikely to be very noticeable in terms of listening levels.
Do you have some specific requirement for more output such as party or club playback system because a more sensitive speaker may be a better way to achieve it.

To get a just noticeable increase in power you will have to double the output power. To get twice the volume out you will have to increase the power by 10 times!
You could bridge two LM3886 chips, but now you are looking at a new circuit and power supply. If the TDA1514 amp still works, keep using it. If you need more power, you need a new amp.
thanks guys for the help... should i change to a bigger transformer( am using 18+/-v output in my transformer), say, 30+/-v, what are the circumstances?
