. . . respectfully disagree. Why would you replace a part that only requires cleaning? If you spend a ~$100 to replace the selector switch (if that is indeed what's wrong) it's no less susceptible to getting dirty again than the cleaned one.
Is my phono stage stuffed
Hi. I have a MF NuVista M3 Integrated amplifier. As of yesterday the left channel of its phone stage has dropped out either altogether and just a emitting a faint scratching sound and occassionally it comes back to normal life but for a minute at most.
I believe it to be the left channel of the phone stage because:
1) I get sound out of both speakers when the source is switched to CD;
2) I switched the tone arm cable plugs at the phono stage RCA input terminals - left with the right and vice versa and still there is no output of the left speaker.
3) I double checked the grounding of the tone arm to the grounding of the amplifier. At a very low minimum volume I induced the typical "hum" generated by not grounding but the hum only occurred in the right speaker not the left.
Any ideas anyone? anything else I should check test. Unfortunately I have no other phono stage to check if everything else is working as it should be.
cheers
