Power Supply Amplifier Hum at Andrew Spears blog

Power Supply Amplifier Hum. Based on decades of years of designing and measuring amplifier circuits and on measurements of electromagnetic interference,. Early transformer developers soon realized that cores constructed from solid iron resulted in prohibitive eddy. Easiest way to trouble shoot if the design allows is either swap power supply cables from left to right making sure of voltage. Noise voltages across the interconnect and wiring resistances that appear in series with the signal voltage and are then amplified along with the. Hums and other amp noises can be a beetch to find and fix. There is a significant amount of dc in the power supply hence why it is humming. Once determined you can either replace that piece of gear or read our. The windings on the transformer may not be. Systematic process of elimination worked best for me. Remove that piece from the receiver, amplifier, or integrated and the system hum should now be gone.
