There must be hundreds published on this forum, but it would take some effort to find them. And then there are those offering boards and kits. All on the forum.

Why Not just make your own Layout???

The schematic is so simple that you should be able to design a compact layout in about 20 minutes......

I just designed a Bridged/Paralell PCB and it only took a Few Minutes and is only about 3in x 3in square.......

Just a Thought.....

And it is going to stay that way unless you actually try it.....

Between the Time you Posted this question till now you could have designed many Variations of this PCB and etched the Board and Stuffed it and Be listening to music by now and Be on to building your second or third Chipamp.......

Also there are not a Lot of design considerations when designing a simple Chipamp PCB becides makeing the Power rail traces thick enough and makeing sure the Feedback resistors are close to the IC and there are Bypass caps close to the Power pins of the IC (Optional)......
