and hopefully someone can offer any knowledge, guidance.
Here's the short - NJ had big storm IDA and all hell broke loose when my basement started to flood. I was going crazy rescuing as much as I could but one of the 57's fell face first into a bit of water. I still cring. I had unplugged the whole system 8 hours earlier but I can still remember the sizzle sound. It was only a short amount of time wet, not submerged, but charging them up again in the living room weeks later I'm hearing a hum from just one panel in one speaker.
No signs of any water or anything else, it certainly looks ok but the one panel makes a very soft hum. No other connections just the wall charge. Other speaker ok, other panel ok. I hooked up a temp amp and all sounds ok for now with 2 speakers setup on Living room floor and mono image in the middle, but the hum must be caused by????
Any suggestions? I do have 2 spare panels and may have to replace it but thought I would ask first. I haven't taken a volt reading and it's not the easiest thing to do with regular VOM's. The last time I measured the panels I used about 6- 1meg resistors in series to allow some kind of un-calibrated reading to compare one speaker to another. I have the latest pwr supply rectifiers from --- I forget the name, Piquet? in U.S.
I'd like to rectify this before the basement is restored in a few weeks as I'm still awaiting the new carpeting. They've been in my family for almost 70 years so I need some help!
