i have a scope (old crt) and am wondering if its possible to evaluate wal warts (smps) or bricks to select for audio applications like running opamp based phono preamps etc. so far im thinking measure the dc coming out and zoom in but that doesn't seem like it would tell me everything about how 'clean' the dc waveform is . any help is appreciated.
yes i know how to make a linear psu with a torroidal and a few caps/transistors but i have so many of these smps things. meanwell seems to be a decent brand and i have some medical grade supplies so very curious.
