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. This link is for more detail on removing the screws from the bottom of the turntable ...

Help! I've been bitten by the vintage stereo equipment collecting bug...here is another 1980s Technics stereo receiver in good working condition. From the looks of it, this was a highly basic model. It offers only 25 watts per channel of output power into an eight ohm load, tuner, tape play/record and turntable inputs. There is no AUX input, although the tape playback input can be used as such. I need to clean up the tuner memory backup battery holder. There is also a capacitor on the main board that looks to have been a little warm, as it was leaned up against a very hot voltage regulator. I may replace it. I also removed a ton of dust from the inside.

Disclaimer: unfortunately I cannot be responsible for damages to your equipment as this is not a common rapier or service procedure and you will be using non original parts that said if you follow the video to every step and make sure you are confident you have the correct parts youll be fine. (Sorry just covering my ars) This is a video showing you how to replace the little pop up target light on the front of your Technics SL MK2 turntable to an LED. the advantages to this are, the LEDs draw less power, they are brighter, they have a longer life span and as an added bonus they work out cheaper in the first place. By the way the LEDs on my decks look blue but they are actually white, they look blue on the camera because they have a high colour temperature. Order codes: Order code for maplin led: N28BY = WHITE. N30BY = GREEN. N33BY = SUNSET ORANGE. N31BY = BLUE. N32BY = YELLOW. Order code for maplin voltage regulator: QL31J = (PART NUMBER: TS7805CZ) OR UJ54J = (PART NUMBER: L78S05CV) When ordering the voltage regulator be sure to check the part number on the part its self to insure you are getting the correct part. Order code for Radioshack voltage regulator: 276-1770 = (PART NUMBER: ML7805A) WANINGS: Dont have the turntable plugged in while you have the plastic case off, i did the test with the multi-meter so you dont have to. Check and double check that there are no short circuits before powering up your turntable, and never allow a short circuit to occur in the lamp ...
