(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.IN HASTE
Beginning homebrew is often the inexperience or negligence cause a wound to themselves, especially on the fingers. Not enough to have in the workshop first aid kit, should still be able to bandage, and the bandage at the end to tie that without help not easy to do.
