(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.AS FROM A TUBE
When sealing cracks and crevices, repair wooden and metal surfaces many assume to use nitroshpaklevok: it quickly hardens. But precisely because of this, the quality of the retrieved from the banks, but the unused material is useless disappears. For storing small portions and ease of operation offered to put filler in rubber medical pear with Read more…
