Headset conversion, again

[[email protected]]

Hello all,

I have searched and read the posted info on converting a military low
impedance headset for use in GA aircraft.

Does anyone have a schematic or have they actually built the lo - hi
impedance transformer and mic amplifer? I hate buying stuff I know I
could build.

Current pricing on the super secret powered amp is $79. It probably has
10 bucks of parts in it. I can follow a schematic or drawing and do
have experience building Cmoy power amps etc.

Thanks in advance for any responses.

This may be exactly what you are looking for, for the mic amplifier!
