I got an old Technics SL-23 as a gift from a relative. It seemed fine albeit turning noticeably slow. However, in my first day of use the pitch issues got worse, until it completely stopped working entirely. The strobe scope lights up, but the motor won't work at all. I know it's not related to the rubber belt, because the motor won't turn even if I take the platter off. I've changed all of the electrolytic capacitors, checked both fuses, cleaned the potentiometers with rubbing alcohol, applied oil to the motor, but nothing worked so far. Is there anything else that I can try? When I turn it on, the shaft of the motor turns just slightly, in a way that could drive you insane just thinking if it happened or not. Please, come forward if you know something that can help. Keep in mind that I'm Brazilian so there ir no deoxit and it is impossible to find a replacement motor here. I know a thing or two about electronics and know how to solder, but I'm new in this audio thing.
