vu meter circuit lm339 12 LM393 opamp 1 used 50 LEDs per channel falls on the pcb drawings have all the parts available in the market

is on the Internet a lot, but the indicator with more than 15 LED Unfortunately, I have found. 2 x 50 LED. I have decided therefore to the design of a simple and relatively cheap indicator with 2 x 50 LED.
