Search Google with phrase, "technics sx-p50 manual". by: Mantius
Apparently it's not hard to get a manual for your Technics sx-P50 at all. I haven't made such a download before but I searched for the phrase "technics sx-p50 manual"(without the quotes) in Google, clicked on the first two results and there was a free sx-p50 manual available in pdf format. All you have to do is download it.
Please note that I can't totally recommend this site or doing a download since I have not tried it personally. So whatever you do is at your own risk. I'm being cautious here. But you can check it out yourself and decide what to do.
