The groove echo comes and goes and is only in the right channel.
Unfortunately, that is the best channel for overall sound in preference to
the l/eft only or a mono mix. The episodes are too long to substitute
portions of the two alternatives, tough I may be able to use the mono mix in
I'm working with acoustic recordings only for this project which limits some
eq options. I may have to bite the $ 400 bullet and upgrade to RX6 and try

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?
