I have been offered a mixing console which I think i like. But it has no PSU and the price is around $100.

So, not much to loose except time and effort.

I found an available PSU for around $2-300, which is still a good deal if the mixer is working.

I should be quite lucky to be able re-sell the PSU because it's a bit old and not super common.

My question: is there a test to at least know if it's alive or maybe even more than that, without having the original PSU?

I am not the type who can build my own
