A crucial question would be what is the period of the echo? (does it match the RPM?) This may on diocate the source of it.

You could make a duplicate track in a DAW and reverse the polarity to cancel it out, perhaps.

It's not really familiar to me with discs but very familiar with magnetic tapes where one wind of a tape can partially magnetise an adjacent wind, resulting in "print through"  pre echoes and post echoes. Perhaps some sort of cancellation of the echo using the actual "non echoed" signal would work. Any chance of a short audio sample to hear exactly what you're describing?

This has proven to be particularly successful using the right wall as the basic file and editing in from the other two files what I can't solve with RX or what is clearly a better capture of a portion of the sound.   Dethump in the declick program is a later stage.  The rest varies according to the specific problems.
