Hello. I was hoping someone can help me with a squeaky noise coming from my tape deck on my pioneer sk-700. It plays fine but has a somewhat intermittent squeaky noise that gets loud at times. Don’t know if it’s coming from the capstan or rubber rollers? I was going to try to oil or lube without taking it apart again but not sure what to use? I have some machine oils that vary in viscosity? Any help would be greatly appreciated. I really like the sound of this pioneer.
