About Nordskov

  1. Hi everybody. I have a PowerTech 2 which have a high pitch tone at around 12-16kHz in the signal going to the speakers. I have done a little troubleshooting. The tone is still there when I disconnect the mixer. It's still there when I turn the gains down on one or both channels. First when I take the power it disappears - would you believe it The speaker cables are okay. Does any of you have a clue of where in the circuit this tone is generated? Thanks, Henrik Nordskov
