LM317T Voltage Regulator with Pass Transistor

To use Amplifiers purchased in USA in India you need 110v step down voltage converter. Use of 110v version in India is not recommended as there is miss match in the frequency.

It's my lucky day because my neighbor is throwing away a microwave! One man's trash is another man's treasure, and with all the parts I can harvest off this abandoned appliance, I feel like I just won the lottery! www.thekingofrandom.com Music by Kevin Macleod (Down Home Rockin) http Project inspired by: MattsAwesomeStuff www.youtube.com WARNING: Do not try this at home. This project is extremely dangerous and should not be attempted without adult supervision and adequate training. Misuse, or careless use, of tools or projects may result in severe electric shock, serious injury, death, and/or permanent damage to equipment and property. Use of this video content is at your own risk. I'm super excited about these salvaged parts, because there are a ton of dangerous projects I can use these for. Like unballasted high voltage electrical arcing, or instantly fatal traveling arcs. How about improvised spot welding, or dangerously exciting metal melting, and even makeshift AC stick welders? I feel like I made out like a bandit on this project, and these salvaged components will lay the foundation for many projects to come.
