Diagnosing THD & Power Supply Problem In Audio Amplifier With FFT Spectrum Analyzer
In routine checking power output and THD with FFT audio software it became obvious there was a power supply problem causing a dramatic increase in distortion with increasing power. Turned out to be an open electrolytic capacitor in the power supply. For reasons I can't explain, it turned up the screen resistor to the EL34's also.
