Audio Watt meter Circuit Diagram with Parts List Audio Wattmeter Circuit Diagram. Notes . If 1A bridge is not available, make one with four 1N 4007 Diodes. The resistor R2 must be twice the power of amp you are going to measure. To calibrate the device, Connect the output of the amplifier to port 1. Also, connect an AC voltmeter to port1.
Audio Wattmeter Circuit with LM3915 - ElectroSchematics.com
https://www.electroschematics.com/audio-wattmeter-with-lm3915/
You need one LM3915 IC and add a few passive components and you got a simple but effective audio wattmeter. This sound wattmeter uses a row of colored LEDs as a scale to show the relative power output of your amplifier in watts. It is easy to be inserted into the speaker box. All you need is to hook a supply voltage to it.
