crown xls 602

galush · 4th June 2009, 01:31 PM

I have a crown xls 602 amp that I am working on. While working on it I broke 2 components that I am trying to figure out what they are and how I may be able to order new ones. The input board to the main board have these two round black components that are soldered to the main board that are labeled LED1A and B and have leads coming off the top of them that go into the input board. They do not look like LED's. I have never seen such a component. Are they needed or could I just run straight wire in place of them. If not, anybody know where I could get them?

Probably a LED light dependant resistor pack.
They may be used for muting the audio in the event of a system problem.
I wouldn't replace them with a piece of wire.
Unfortunately, I opened up a few XLS602 amplifiers yesterday to clean them out (blow out the dust). It I had waited another day, I would be able to give you a better answer.
