changes speed

  1. tusntuk2

    Pulsing buzz varies speed with Volume/Bass. Any ideas?

    Kenwood KR-5600 receiver, just finished recapping Audio and Power Supply boards. After resetting bias it started making buzz/hum in a rhythmic pulse that would vary speed as either the Volume or Bass control was moved. Right channel only. Maybe some transistor oscillation? Haven't had one...
