Robert, Get the book, "On Pitch" from the guild store. It has sections where you use the ETD like you would for aural tests. In so doing you will become more familiar with the partials you are supposed to be listening too. Ghosting can help too (sharply playing the coincident partial while holding the interval notes and listening to the after-ring). It is one of the few references that really breaks down tuning to its basic parts and allows you to understand what you are trying to accomplish. Good luck, Andrew
