All resistors are 1/4 watt, CFR 5%, unless otherwise stated. You are great! You are most welcome. For AC power supply, amps are equal to watts divided by power factor times volts. Amplifiers and inverters are generally rated with higher operating voltages so that the current (amp) rating could be lowered….as we know that Watt = V x I, that implies if the voltage goes low, the current has to rise and vice versa. I have been looking for a good stereo amplifier circuit diagram for a long time. Ok then I will try but in the mean time I have all the parts and I keep trying to make it work, I even tried in on a new bread board with new wires thinking it was a connection problem but still nothing, the only time I hear a hum of any sort is when I use my finger to touch the zener diodes I hear a hum from the speaker, I was wondering If I should just build it on a Vero board because I reall need it this week and a pcb will take so long because of my location, I am wondering If I should just use the parts from the older version in the circuit in this article, In bread board the possibility of a connection fault is more likely than on a PCB….moreover mosfets prefer short connections and therefore work better on correctly designed PCBs.Veroboard can also be problematic due to their closely etched pads which can cause hidden short circuits or stray inductances, I am going to pull up the circuit I built on the proto type board and start again and ensure no mistakes. Might need some electronics component be equivalent to these from collector like it is a mini RF amplifier. An astable multivibrator just 12v 50w audio amplifier only, 2020 - Abdul.
