Hi All,

I am from Mumbai, India. Just bought an AV receiver (Yamaha 665BL) from USA. Can't wait to take it apart and learn what are major components and how to they fit together.

Primary motivation (at this point) is to learn how to change power supply so that it works with 220 V electric supply in India.

Great to find a forum full of Information on DIY.
