How To Make A 75 To 300 Ohm Matching Transformer

Distorted Sound: ​Ensure input signal isn't too hot (clipping). ​Check speaker impedance matching. ​Inspect speaker cones for damage. ​Look for faulty components in the signal path (capacitors, transistors, ICs). ​Poor power supply regulation can also cause distortion. ​Humming or Buzzing: ​Ground loops: Try isolating components, using ground loop isolators. ​Poor shielding: Inspect cables and internal wiring. ​Faulty power supply filtering: Worn-out filter capacitors. ​Proximity to interference
