I am currently learning about electronics in my spare time and one thing I am trying to get a better understanding of is transistors. My plan is to build an amplifier using transistors, most likely just using pnp or npn, that will be good enough for me to want to use.
The schematic I am thinking of using: http://www.zen22142.zen.co.uk/Circuits/Audio/headphone.htm what do you think of the design?
This will also be a good opportunity to design a dual rail power supply. I bought a transformer that can be wired up to work as a dual rail a while ago. Would I be able to use a zener diode controlling a transistor, can't remember the technical term for this, or would this cause to much noise? I have read that amps are insanely sensitive to distortions in a power supply.
Would it be best if I use metal film resistors or will carbon ones suffice?
I know that the wattage of an amplifier does not refer to the power drain at the plug, how would I find out how much power the above schematic would require?
This may seem daft but I am new to this, what does +Vcc mean? I read that symbols like it should only be connected to identical symbols but it is alone on the schematic.
Thank you
