                  with magical surahs from holy Quran on your lips you can find gold without the cat and Delta Pulse.

                            What's new in the scheme? Two LEDs are united in one double. I do not see another new one.

                            • the schematic is same left. new -

                              -- you can set 2 LEDs or bicolor one
                              -- sockets were changed on another 'pops screw style' type http://www.ebay.com/itm/50pcs-2pins-...gAAOSwpLNX~Lut
                              -- grid poligons, cause was hard to desolder in some places
                              -- transistors' position in voltage indicator was fixed
                              -- general optimization

                              • Does anyone have a listing or diagram of Delta / Sniffer trouble shooting test points with nominal expected voltages ?
