i have a pair of even tr6 monitors. i've been pleased with them. but
one of my monitors has started to fry tweeters. my tweeter burned out, so i wrote event, and they sent me another one free of charge...which was great. but the new one was only in there for a few seconds, and it literally started smoking. so i metered the positive and negative wires going into the tweeter, and noticed that there is 50 volts passing through them. i checked my working monitor, and there was no electric current at all passing through those wires. does anyone know what is going on? can i fix this? any help would be much appreciated. |

Is it DC or AC? Definitely it's something gone wrong with the amplifier stage. If it's DC, I'd look for a bad output transistor or a bad supply rail. If it's AC, it's time to start going through the circuit with a scope and seeing what is oscillating. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
