Montana EPX. Not powered. I did a lot of cable switching tonight to see if the noise jumped to the other channel. I also found two of the fuses on my right BAT VK150 monoblock blown. I'm now trying to figure out if it's an amazing coincidence that the amp happened to have an issue (tube? --- they're not that old) the same time I intro'd the 390? Or, did the noise that initiated at the 390 create enough of a pop / spike that it was the root cause of the blown fuses? I replaced the fuses, switched the XLR's out of the 390 to see if it jumped sides. I heard no further pops. Switched them back to normal and have still not heard anything. Not sure if it was bad cable connection? Seems unlikely, but I guess it could have been dust or contact issues on the connector of the 390? I bought it from original owner who said he has perhaps 40-50 hours on it at most, and it has been disconnected for some time now (he's now into High Res digital audio). I'm not sure what caused it. And I'm not positive if it's gone for good? Any input is appreciated. Thanks.
Levinson 390s -- intermittant loud cracking sound
I just picked up a new (used) 390s today. Sounds great, but every so often it emits a loud popping noise out of the speakers (seems to come from the right channel). Almost sounds like static-electricity discharge through the system. My understanding is the unit has low hours, original owner, and it hasn't been hooked up for quite awhile. Is this normal and just the unit re-charging capacitors, etc, so to speak? Or is this an indication of a problem? Thanks.
