Question about ATI Audio Players & Recorders
All of a sudden we're getting a buzz from the front left side of the power amp. I opened it up and there's a block that's buzzing under the Tamura 3FD-412. Any ideas? Both fuses are good..

If the problem is present with ONLY the speakers connected, that is no other powered devices like subs, or input/output cables, it will be a power supply problem inside the amp. If you have electronic fault finding skills, there will probably be a capacitor in a regulated rail that has failed.
If you do have a sub connected, be sure it is powered from the same mains source as the amp, or at least a GPO that is on the same phase. Different phases will induce mains hum, as will multiple earths. Try also temporarily moving the amp(whilst monitoring the hum) from where it is sitting and see if the hum is being induced into the amp by any other devices
Happy to talk to you more about this. Just ask:)

If your volume is down and there's a hum, then it could be that your capacitors in the power supply are blown. Also there could be a problem with the bridge rectifier, possible that there's 1 or more diode's defect. Any technician can reapir that.
Hope it helps,

If it's buzzing when the car is moving. it could be the wheel bearing making the buzzing sound. it needs to be replaced. you can probably hear it as being inside the hood.
