nbcd said:i have a SHARP amplituner that has STK459 as final amp stage with 2x15Watt power and it burned out.Can i replace it with a STK463 whick is rated 2x25Watt ?with no fear that the amp will sound good as before
Making a new supply for the new chip may be problematic. Transformer + bigger caps may not be easy to fit in the box you have.
I would stick with the same chip or make a new amp.

Yes, you can. Power output will be the same as on the 459.
