ricksaudio,

Roberto is correct actually he all the time. :D

I have a pair of Sequel II's and the panels were replaced and they sound excellent. I bought them used about 2 years ago and the panels were replaced on them about a year before I purchased them. My Sequel II's were one of the first off the line (1989) and are still running fine.

I did have to replace the power regulator boards which is very easy. These boards are similar to the latest product of the Sequel II's/ SL3 time frame that shuts off the voltage to the panel after a period of "no activity".

Hope this helps

Good Luck

Jeff :cool:

Well thanks guys I now know where I stand with my panels,as for washing them with warm water does it really help,like I say my speakers are still working but they sure do like the power,I ended up purchasing a moon w-3 power amp to drive them,and I just think they are a bit low for sensitivity.I plan to clean up all the solder joints and trim the wiring that was exposed that looks abit contaminated.As for washing I clean both sides ;)

It made a difference on mine...but how much compared to new? But it helped, and yes I did both sides of my panels...

Did you see my Washing thread in the Tweaks? I cleaned panels and electronics.

Don't worry!

ricksaudio,

If you are referring to the front and rear stators separating along the vertical edges, don't worry, this is quite common. The stators are bonded at the top and bottom, but only held together by double sided adhesive tape on the sides. When the panels are installed on their frames the stators are clamped together as they should be.

No need to tape or glue them back together.
