100W Audio Amplifier

When I was around 17 years old, I acquired electronic habilities during my free time. Music also being one of my hobbies, I decided to use my electronic knowledge to build an audio amplifier. While my amplifier is not the most powerful that exists, it outputs a good quality of sound. It also has succesfully passed the party test . This means it has played as loud as possible without (intolerable) distortion for many hours hours, in a 3-4 ohms load. Power-supply:I used a 110 volts to 50 volts ac transforer with a center tap. (this means +50 volts and -50volts). Next, I rectify the current with a diode bridge(big enough for 8A), and I filter with 2 big capacitors of 10000uf each.
