[QUOTE="W. Mark Hellinger, post: 42153, member: 692"] Re: Flakey PM-4000 mute groups Sage advice Tim. I checked the power supplies right off... they appear to be delivering correct and stable power. Also, the board is powered via primary and back-up power supplies through a Yam SU4000 switcher. I suspect the problem is in the TB module (which contains the mute group masters)... I vaguely recall trouble-shooting and fixing this same (or very similar) problem in a PM-1800 and a couple of PM-3000's... but it's been years ago... and I didn't keep notes... and my brain got filled up with other stuff since then.
