Nice system! White is a lovely color for audio gear, isn't it?
There were many records in the old days with a very low frequency rumble that was due to (uneven cooling I think in) the pressing process. Many preamps/receivers of the day came with what were euphemistically called "rumble filters" ;--)
But "high frequency reverb"? Do you mean "feedback"? I ask because high frequencies don't reverberate (either naturally in space, or through artificial electronic means), so I'm trying to figure out just what it is you're hearing.
If I had to guess, and since it only occurs in that one inter-band space, I'd guess it was electronic feedback that somehow got into the final master tape or the cutting process itself.
I've never heard what you describe -- what you often hear on older records is the faint sound of tape print-through just before the next band actually starts.
