Phantom Power Microphone Pre-Amp
Switchable microphone inputs with Phantom 48 and 12 volts. In good working order
This is the microphone preamp that is switchable for 48 volt Phantom, 12 volt "T" which also has 200 ohm dynamic
If you have a rubber bung in the left side of your NAGRA, next to the handle fixing screw, all you need is the rod with a plastic washer that fits in the hole. Then solder the rod through the hole into the preamp switch. The amp fits in the same way as the other microphone perms
NOTE: You will not need the red and white lead, unless you have another phantom preamp, that would fit next to it and is not the same.
