Need help on McIntosh meters


Has anyone every had a McIntosh meter issue? I have a McIntosh MAC 6700 and my right meter hardly moves yet sound is fine on both right and left speakers. My McIntosh MX120 and my McIntosh MC206 meters all work just fine. Could this be due to volume being too high at some point that could cause this? Looking for some remedies, thanks!

No, meter is defective.  Easy fix if new meter is still available.  I replaced one on a MC152 amp and it took less than 30 minutes start to finish. 
just a thought, try flicking the meter face with your finger, I did that on another McIntosh piece and it brought the meter back to life.  I got my meter from Audio Classics but I think they are closed until the NY Governor says its ok to open again.
