LM317T Voltage Regulator with Pass Transistor

This is a video showing you how to strip a technics 1200/1210 back to its face plate. The reason for doing something like this is either to pain the face plate or to replace it, in either case stripping the turntable back to the face plate is required. Just as an experiment I phoned my local electronics repair shop to get a quote on how much he would charge to do this and he said 20 quid setup charge 40 quid to strip it and 60 quid to put it back together 120 QUID !!!!!!! Thats like 170 dollars I could buy a second hand turntable for that alternatively 85 quid to simply change the face plate thats like 120 dollars, so you are defiantly saving a bomb by doing this yourself. Its not massively difficult you just have to have your head screwed on and pay close attention to where all the bits went, if you think about it the main circuit board, the power circuit board, and the transformer are all joined so youre not going to put them back in the wrong place and you know where the tone arm goes and the pitch fader, and if you have ever switched on a technics turntable you will know where the power switch is, so you cant really go wrong. Information. When soldering on these turntables especially the older models leaded solder is normally used so keep your soldering tip clean after soldering, and mind your fingers because sometimes leaded solder can bubble and it spits and itll burn your fingers.
