No sound in left channel on red LED on in 2ce's

Hi, I have a VTL 2.5 pre, Belles 150A amp, vandersteen 2ce's, one vandersteen sub, VPI scout.

Yesterday, I was listening at a low volume, and I heard a loud pop. Then, a red LED lit up in the left channel 2ce speaker. There is now no sound. I was worried it was the speaker and wired the right speaker to the left channel on the 150A, and the same thing happened (red LED again, no sound, but no pop this time). Both speakers work fine through the right channel. I also disconnected the VTL preamp and subs from the 150A and same thing happens. It appears to be isolated to the left channel of the 150A.

Any ideas?

thanks in advance!!!

The red light ususally illuminates when the speaker is over driven. In your case you probably have a problem with your amp. Maybe it's outputting DC? You could call Vandersteen to see what activates the light, other than too much power, and then give that information to a technician to troubleshoot your amp.

More likely it's Belles amp needs 'left leg surgery' and that's where I would establish contact since your Vandys are working fine through the right channel. Did you try to swap preamp channels?

sounds like you may have blown a fuse on the left side channel of the power amp?

Thanks everyone!

@Marakanetz - I think it is the Belles... I called Dave Belles, and he said to mail it in. I completely disconnected the preamp channels, and the same thing happened, so it seems to be completely originating out of the left channel on the Belles. Luckily, it is only 3 years old and should be under warranty. The downer is the likely long wait I will have!
