I have an Amiga 600 that i never use. Its in the original packaging, even with the original silicone humid pack😅 anyway, its taking up space and i want to sell it.

I understand that the 600 might have some capacitor problems and these might need change.

And if it needs that, then that's a problem for future me... Right now I would like to know if it works, and I don't have any TV work coax input...

So I really need a cheap device that I might use a few times just to know if if works before and after any repairs.

What du you guys use?.
