Microphone Preamplifier

Another weekend project is this microphone preamplifier which came from my new book Hints and Kinks for the Amateur Radio. The amplifier is a single transistor powered by the 8 volts from the radio transceiver. I can't find any vintage desk microphone casing so I ended up with this pink jewelry box which I obtained from a novelty store, anyway the output audio was very nice and a little treblish. All the needed parts are available at my favorite electronic store at very minimal cost. ---73 de hevir
