Really. It's 2024 and nobody is selling a simple line/speaker level module with mains level connection and amp/component main power socket?
I have short-term need for one and thought I'd have it in a couple days.
I've found a good project description but the required NJM2072 IC alone is going to cost at least $15 by the time it is shipped.
For that reason it looks like this board is my best value to begin the project. Anyone familiar with it?

I have described such a project (and I am presently using it whilst writing this post):

It is a bit more sophisticated since it includes an automatic selector, but that's basically it

That's a superb looking and I suspect very nicely performing project! Great compact and versatile design with transparent operation!
I've never used proto/perf board and that looks like a worthwhile place to start should I have permanent need. I've etched a few PC boards for very basic circuits. As you said, it's not as complicated as it first appears, yet it is certainly a challenge to my skills.
I'm flabbergasted that there is seemingly insufficient demand to support such a device on bulk scale.
