I found it. It`s this thing:

I can actually see it trying to engage when I plug in. That is *definitely* where the
noise is from. If I rotate the motor with it on, the noise changes depending on where
the rotation is at.

It would actually be coming from the motor not the reader. The motor for the papertape
reader is either in the pedestal (if your ASR is on one) or somewhere in the UCC-6 (the
power supply). You have to follow the cable that comes from the reader along the rim of
the chassis.

Good question. I only thought motor because it seemed
like the noise
was from back there. And when I put a plastic tool against the outer
casing, I could feel a vibration. But now I'm wondering about that
paper tape reader.. when I listened to the noise again it did kinda
sound like it might be coming from over there. It's kind of diffuse.

stupid question - you're certain the motor is making the buzz and not
the reader motor or somewhere on the UCC-6?
