  1. Thanks. The amp is definitely not in Bridge Mode. I've just checked. It's running right now. Been running for the past two hours at a low volume and the fault has appeared again. The amp seems to output fine, equal on both channels and no distortion. I've been playing with the gain knobs on both channels and when turning one round back to '100' it cuts out '21'. The other knob seems to cut out when moving the spindle in and out slightly. So the problem might have something to do with the gain knobs? Just also thought i'd say the K series are outstanding. I have five way system which consists of two K1's for compression drivers and super tweeters, two K2's for mid and bass and a mighty Crown Macro Rerefence Amp for sub bass.
  2. Hi, I am currently running a Crown K1 in a 'Y input' mono mode, where one input is driving both channels. The problem is after about and hour when the amp gets warm to hot the signal light on one channel seems to be on more often than the other channel. Also, the gain on one of the channels has no effect on the output. If I turn the gain knob all the way down the amp still outputs on that channel. Switching the amp off for a while and switching back on seems to fix the problem for a little while and then it returns.
  3. Amcron Micro-tech 1200 with a D6304B2 board. Found fan seized. Un-siezed fan, Fanformer windings brown and when powering up it gets hot. Suspect short circuit. Disconnected output to main board and fanformer runs cool. Visual inspection found power supply components on main board capacitor C4 brown/burnt and has full continuity running through it. I'm just wondering what the output of the secondary output should be on the transformer which powers the main board? I've measured around 24v AC on the red and blue wires. Some say it should be 15v and others say 18v. Looking at a schematic from another Crown Amp with the same main board it says 24v. Bit confused. Thanks.
