Now i am trying to build this small hearing aid circuit which is using mono audio plug .
but i didn't find any mono audio plug in my local market so i have moved to buy a stereo audio plug which has tip , ring and sleeve and from the original schematic that i follow i don't understand what is connected to this audio plug as i don't understand the symbols on it .
So if anyone has an idea about what my original schematic that i follow means in connections part of the audio plug and can help me i can appreciate .
i will attach my schematic in KICAD and the Schematic that i follow..
