In my experience, tape with SSS squeals, first softly and possibly
intermittently, then progressively louder, causing easily apparent
distortion as it squeals. Not so much a noise as bad distortion.
You might also run the tape thru 2 of your fingers. If it is severe
enough, you can easily feel the stickiness.
If you only hear the noise on the recording and not coming from the
machine itself (like mechanical noise) it is possible the tape was
dubbed from a source suffering from SSS.
If you are hearing a noise, like a steady state noise, I might suggest
it is something else.
What is the source of the original? was it a live performance in a room
with loud fluorescent lights?
Pinning it down to a specific frequency like 11,100 doesn't seem like
SSS to me.
