I have aquired the above mixer. it has 6 chanels on it. it seems there might be a problem with it possible missing wires I am not sure. does anyone know where I can get scematics and more information on this unit. the inspection sticker on it was dated for 1977. please email me with any information I dont know when I will be checking this forum again. I will be gone for this following week also. thanks for anyhelp you can offer
