Making power amplifier 30 – 100watts

Now this is an interesting amplifier and can be built for almost any AF power level you want from or more. I will give you suitable examples for the 30 – 100watts version. RV must be set to minimum resistance before application of power. To set up the amplifier, advance RV SLOWLY whilst monitoring the […]
