(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.“HAZIRS” FOR BRUSHES
To the hair part of the brush is deformed during storage, they usually put a pen in any vessel, at least — hung on a nail. Offers another simple way of storage. Take the PVC conduit and through suitable intervals (the size of the handles of brushes) nail it to the wall or door of Read more…
