Since line-in works on my nano, but mic input does not, I need a cheap, small preamp that brings my mic to line-level. I don't want to buy anything, but I got lot's of old devices with almost any type of transistor, resistor etc.
I searched the web, but I couldn't find a working (simple) one anywhere. Can you provide me with a plan for a preamp? I doesn't need to have good quality or be stereo.
Any suggestions?
