Default ZR1600 Problem

I measured a stange signal on the right output of my ZR1600 at idle. Look like a sawtooth at around 675khz , 2.5 volts peak to peak. Any idea what could be the source of the problem?

I know but is it normal that this signal is present at the output?

No, the clock should be attenuated by the output filter. The output filter could have died on you. Also, the speaker's impedance at that freq may mean that the clock won't be reproduced. It's best to remove it, however.

BTW, is this signal also present on the left channel. That would indicate whether you have a problem or not.

I measured the signal at the tweeter end. There is a constant hiss but barely audible. 2.5 volts P.P on both channel
