With all the TT705 mic discussion I pulled my instruction sheet out to see just what it has to say.

"The Model 705 incorporates a momentary type Push-To-Talk (PTT) button (gray), a Push-On, Push-Off locking type button (black), electronic circuitry to switch the microphone on, a signal amplifier that adds 13dB of gain to the output level, an attached output cable and a battery compartment for a 9 volt alkaline battery"

.........stuff skipped
ELECTRONICS: C-Mos PTT switch, C-Mos signal amplifier, NPN T/R transistor.
CURRENT REQUIRED: Receive mode: Less than 2 microamperes.
Transmit mode: 2 milliamperes typical, with 9 volt battery.

Yes it has a preamp. See my question about how mine draws around 16 ma which
seems like a lot.
