You asked easy questions. I'd ask why enabling Dolby-B while playing a cassette tape seemed to reduce the high frequency output. I didn't expect any of them to be able to correctly answer this, but I wanted to see if they attempted to snow me and how they handled themselves when encountering an unfamiliar situation.

30 ounce tracking force would certainly clean a layer of dust out of the groves (along with some vinyl)! But, you'd need a specially reinforced stylus and a fortified head shell and arm lift in order to complete this task.

Was this an older person?
