2 questions please:
1- The curly phone cord has 4 wires inside(2 for MIC +2 for spkr) , did u connect them all in parallel from both ends, or used only one wire & ignored the 3 others?
2- The transistor u used is general purpose NPN silicon..did it work ? in this case can we use 2N2222 or C8050 for example ?
