(Four steps to excellence). 1. Noise reduction (background with a frequency of 50 Hz). In parallel, each diode in the rectifier of the AC power supply (PS) located in the body of one of the speakers, connect a non-polar capacitor type КМ6 (or similar) with a capacity of 0.01 microfarads. In addition, the parallel output SP to filter the background set compact electrolytic capacitor HITANO company with a capacity of 3300 UF at a working voltage of 25 V is ineffective capacitor 1000 UF. These simple improvements reduce background noise with a frequency of 50 Hz present in the cheap versions of the speakers made in China.SCREW FROM THE NAIL
Homebrew joke about the fact that the screw hammered by a hammer holds better than a nail wrapped with a screwdriver, I remembered in that moment, when it took a fairly long screw M6, which Arsenal was not. This joke led to the idea to make a screw with a countersunk head of a suitable Read more…
