I built a  sound mixer  11 years  ago.   Two phono  sources, two line
sources, a Mic., Cueing.  

It  used BiFet  op-amps (TL084),  audio taper  potentiometers, a tone
circuit borrowed from  the National  Audio Handbook,  two great phono
preamps  borrowed  from the  now defunct  Advent Reciever  (I made PC
boards for these), an op-amp mike preamp, a couple of radio shack LED
V-U meters, a box, power supply, and about 50-70 hours.  

As a new grad with time and  no money,  it was  fun.   But I wouldn't
repeat  the  process  today  seeing  some  of  the  low  cost  mixers
available.
