Hi folks, haven't posted here in a long time but logged on to check about a similar issue I see being discussed here so rather than start a new thread I thought I'd ask for advice here.
My EP600 is once again acting up. It was new 4/06 and has already had the amp replaced once about 2 years ago. Now it is acting up again. 2 nights ago there was a lot of popping in the speaker and then the dreaded very loud 60 cycle hum. I immediately un-plugged and after plugging it back in it went away. The sub is on it's own dedicated circuit with a Belkin AV Pure power conditioner / protector. Never been a ground loop problem before and have no reason to believe it is this time. I don't abuse the sub at all and frankly to have it start to act up again is a little disconcerting. I called and they were fine to talk to and suggested I remove the ground screw. Nothing changed. Still humming. Put it on a different circuit....same thing. Whether direct or through power protection. And it's always had a slight burnt electrical smell to it. Especially when warm. But so did the original.
They also looked up what was wrong with the last amp return and the notes said it was fine. Nothing wrong. Which I find very hard to believe believe cause I was able to take either an XLR or RCA from my pre amp, plug them into the EP600 and nada. But then take those same cables and plug them into either a 20 year old M&K or my EP350 and they worked fine. So if the amp wasn't dead then it must have had a voodoo curse on it or something.
Anyway, what to do? It seems to be working OK now again, albeit with a very slight hum that's only audible if it's dead silent and you're close up. But I'm already gun shy on this thing. I've got less than 6 months till the warranty is up. So do I bug them for a new amp? Again? Wait til it's completely dead?
It seems that I'm not alone with these issues. What have others done? And did the new design or version fix these problems? What exactly is dying in these things?
Thanks
