…i have many electronic problems, first there is my walkman; it worked great for years, then it started playing a bit slow, battery light was strong, but i switched to fresh batteries just in case but the problem remained, i tried cleaning it with WD-40, since i thought it fixed my reciever, but now i’ve started a new mix tape and have the same distortion problems, i’m not sure if my reciever is just old and the conections are shot and it is time for new component, or my tape deck is a dud, and now my walkman won’t work at all, could over use of WD-4o cause more ill than will in the insides of a walkman?
