I want to modify a superscope ec-3s microphone to have a hotter output: line level, but still unbalanced.
I’ve modified a couple of these mics to work with typical microphone preamps once by impedance balancing and another time by adding a transformer output. In both cases, I just left the 1.5v battery rather than trying to use phantom power. Great sounding capsule, but its all packaged up with a fet and source resistor. I have been leaving those little capsule assemblies intact.
This time, I want to use the stock 1/8” output cable, but have the output level be much much hotter.
Im ok with burning up the AA battery relatively quickly to supply the current necessary to get the amplification. Or if 3.7v is necessary , im open to a different battery
Stock circuit looks like this:

Highish output impedance is OK in this case.
