Happy New Year!
Can anyone recommend an opamp (single or dual, preferably through-hole) that can provide clean gain of up to 40dB noninverting, from a source impedance of 15K to 20K, powered by a 9V battery?
Now, maybe you don't, or shouldn't, grab the ribbon for far-harpsichord, nor the hot condenser for snare-kissing... yet often we do.
... and what frequency can you hear?
Does that mean then that in order to get decent amplification of stuff we can actually hear, you need good amplification of stuff we can't hear?
