Noise problem
Hi..!!!
Try to figure it out...
your power supply is too noisy but we have to know what is the real score or what is the load of that power supply...
If your power supply is too small than the load of course it will create a noise like it is vibrating..
If your Transformer core is not fit to its boobin or it loose also it create a noise and the capacitor is not exact it will also create noise....
The most thing to rememder is to determine the exact load of your power supply because it make your power supply damage and when too large power supply to a few or small load it will damage your load...rememder the current...
