Crown CE2000.......Under the hood

Hey all, I got a problem with my crown CE2000 power amp. Last night during rehearsal, channel one became very quiet. I still puts out sound but not near what you would expect. Channel 2 seems fine.

I opened up the top cover to see if there was anything obvious wrong.

I noticed four "beads" of what appear to be silicon covering four unknown components. Two of these seem to have had a "thermal excursion" because instead of the silicon looking shiney, these two look like foam insulation.

Anyone have anyexperience with these amps? Ever looked inside?

Thanks

Denny
