O coarse I have just aquired a R-86 and seemed to have solved most of the problems that has come with it. However there is no sound control button on the machine anywhere(usually on back). I really looked well. There are some red and black wires cut off inside the amp cabinet area which I think maybe from the original sound control. I can hear the amp humming when the record is playing and when I push down on the outer can control I can hear a loud clicking sound as the amp is attemping to make sound. I guess my question is if I do not have a volume control will I still get uncontrolled sound from the machine or is this my problem. All thoughts or ideas are welcome.
