Good morning,
I'm trying to build a battery powered electret preamp for use with aviation radios and I've tried a couple of circuits I've found on the net. Unfortunately, while I get enough amplification to use through a mixer in my studio, there isn't nearly enough output for use in an aircraft. I'm getting about 50mV peak from these circuits but I need about .75V at 1kOhm.
Could anyone point me to a higher output circuit please?
I can post the circuit I'm using now if needed. Perhaps I just have to tweak the resistor values but I'm not very good with the math.
Thanks,
Tom.
