	I missed the start of this thread but remember the microphone 
needs some volts across it to make it work.  It will be either an electret
mic with a built-in amplifier or a carbon microphone (very old and noisy).  
The SB16 is unlikely to supply this voltage (I'd check if I had one - sob, 
sob).

	Once you have a power supply for the microphone you should get
plenty of audio signal from it.
