hi, i just found an old inear stuff, philips SHN2500, in a box left in my storeroom. It still works well but i see that It doest have portability with a small size amplifier sticking with the cable. I want to separate the amplifier by taking out the plug and headfone wires and solder some female plugs onto then put the board into a new box.
but the electric board looks like below with the presence of
Left, LS, RM+
Right, RS, LM+
My questions are:
- do LS,...
