In this video 'Setting Bias current for 20 Watt Class A Amplifier', I will show the math on how I come to the bias current level, and then I'll show the schematic to point out the parts involved. I'll then set the current level.#20Watt Class A bias current, #ClassABias, #ClassAAmplifierbiassetting, #AmplifierBiassettingexplained, #ClassAamplifierbias #20WattClassA

Thank you for the great video. DC measurements with temperature too, just what I wanted to see. I have seen heat sinks saturate and temps rise over time without fans. We don't want fan noise. i have to see more videos.

Thanks for your feedback! I thought about using a small fan to slowly move the air to help with air movement and cooling.

Great stuff …when playing music with class A. More power will be dissipated by speakers than sitting idle with no music ..so it should be slightly cooler at high volumes??
@KissAnalog
@KissAnalog Год назад
Thanks for asking. Well it probably won’t get cooler as the bias current is the minimum power dissipated:)

hi edy, can you make video how to calculate efficiency of this amp in microcap. maybe a series about amp measurement in microcap, thd, pssr, slewrate etc.

Thanks for the great suggestion! I will do that very soon;)

Actually the one I chose I like the best because of the voltage range:)

Distortion is your friend when it comes to music all instruments/ recordings have distortion. 1% is quite acceptable

Thanks! I can’t disagree:)

Why was 8ohms chosen?
@KissAnalog
@KissAnalog Год назад
Great question - thanks! It doesn't actually matter what load is used to set bias. Bias current goes through the output transistors but not the load. I tested this amp with 4 ohms in part of this series (it is in the playlist).
