The amplifier you design is only half oscillation 😂😂😂song amplifying lmao Use +12 0 -12 and design in class ab type give base driver transitor of 5v 1.5a max and you will get 150w 4ohm output
It's amplifying only half oscillation of the song.. I did that experiment it's not clear but I was amazed just half oscillation still produce sounds lol
I feel kind of bad taht you have no comments or thumbs ups. This is a nice little video, though if I could make quick suggestion...talk. Giving people explanations and explaining why you choose the particular components and what they do, etc. would go a looooong ways. Plus I'm sure some aspiring Electronics Engineers or home DYIers may be looking at this and wondering "What is that...why did he choose to use a 1K resister....what are those twisty things and how do they work". Explain the legs of the transistor and the terminals of the POTs. Great video, though, none the less!
The 1k resistor limits the current via the Zener. The Zener limits the setting range via the potentiometer. However, the set voltages are not load stable and drift away. Based on cable cross-section and heatsink size, I would prefer LM317 (+) and LM337 (-). If the max 1.5 amps is too low, you can switch to LM350 (+) and LT1185 (-) for max 3 amps. Alternative to the LM350/LT1185, if you will work without the protective circuits of the regulators, to amplify the current via a power transistor. The Tip41/42 would be better used here, as there is now a voltage regulation.
