because they don't know the words? :lol:
Ok, i have some old pc speakers who generate a low humming sound, not affected by volume settings.
After googling some i noticed that the sound remained, even if they were only connected to the power plug (which would eliminate a ground loop if i'm right).
The model is a ys 300 and the transfo (hope this is good english) is inside the right speaker along with a small pcb with some caps and stuff.
My question is pretty simple : what would produce the noise - is it the transfo or some fault on the pcb?
Oh, i also moved the pcb as far from the transfo as possible without noticing a change in volume or pitch.
These are OLD speakers, so it is probably an age problem. :wink:
