LM317T Voltage Regulator with Pass Transistor

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.

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 ...
