Audio Experts advice on LM4780 PCB

Strange reasoning, but okay.

- Avoid reflections that may superimpose on the signal. Even if you think the frequencies involved are too low for it to make a difference.
- Keep the traces as short as possible. A right angle (or worse a sharp angle) produces a longer trace than a curve or two 45 ° angles.
- Reduce inductance. A right angle produces a higher inductance than a curve or two 45° angles. Even if the additional inductance is so small that you may be tempted to think it won't affect audible frequencies, it is simply good design practice.
- Keep the cross-section constant. If you think about the analogy between current and water, you will easily understand, why.
- Heed the advice of university professors and/or experienced designers and/or textbooks. There is usually a reason why they teach or do things in a certain way.
- It costs the same and looks better.

and the tight 90degree angle prevents the chemical reaction that removes the copper from happening properly.

Good point.

Woow..Point to be noted.

Thanks, it's getting more intresting here then i have thought.

Amp PCB updated.
Removed all right angles. Moved Zobel to Speaker connector PCB.
Speaker Grn will now come from PSU board.

IF it's ok now can i make a sample PCB.
