He could have used a 1A4 in a 547 (or similar), fed this 1A4's output into one input of his 556's first 1A4, and used the remaining 3+4 inputs of the 556's two 1A4 units. 4+3+4=11.<br /><br />My 556 quit working about four weeks ago. It blows the fuse of the mains outlet it is connected to. I hope that I will soon find the time to do a 'scope sunday and fix it. Maybe it's only a rectifier diode or cap right behind the transformer.zebonauthttp://electronics.stackexchange.com/users/930/zebonautnoreply@blogger.com
