Hi, there.
Arcam Alpha AV 50 amp, only connected the power cord with source input.
Then, connect speakers, a low volume noise from the tweeter.
Use an oscilloscope and measure a 100 MHz signal at the speaker outlet
behind the amp.
Disconnect the speaker wire, same 100 MHz signal. Disconnect the
power cord to the amp, same 100 MHz signal.
Question: Could this 100 MHz signal causes the speakers to put out
some subharmonic audible noise? What else could be wrong? Where
should I look for the problems?
