HELLO EVERYONE! I have two Technics SL-PG390 CD machines and I have recently changed the laser transports in both of them as I was having issues with playing CD's. Well, I am still having issues as one machine some discs will play through no problem and the on the second player it sticks/jumps and is generally being a pain. I am wondering if the laser focus needs tweaking on the first one and lubrication on the second. If I can't get these sorted I may have to take the drastic action of getting rid of both them and just use my Rotel player which is 26 years old and never had thing done do it. Many Thanks in advance guys!
