OK, I have a pair of JBL 3-way studio monitors in the basement that are being driven by an older Adcom 200WPC power amp w/ separate Adcom pre-amp.
Anyway, yesterday while listening to them at half volume, they started to make a loud clicking noise; first one channel and then the other. The clicking does not ocurr when the amp is not driven hard - say 1/4 volume.
Is this systematic of DC voltage being dumped into the outputs by the Adcom power amp?
I'm assuming this would be very dangerous to the speakers.
