" There are no mono fold-downs from stereo masters in the entire Tone Poet series, period."
Confusing...
The link contradicts this:
" As good as the mono originals are, after the October 30, 1958 session at Van Gelder Studios the mono masters were made by folding down the original stereo master. Once we heard the actual stereo masters, the decision was made: when a stereo Blue Note master exists, we will use that stereo master to cut our lacquers for this series."
"Let me be clear the Tone Poet is a stereo record."
billstevenson, is this is the album you have? I'm confused.
Hank Mobley – Hank LP (Tone Poet Vinyl Series) - Blue Note Records
This is a mono LP. You are referring to the original stereo master folded for the mono used for the LP?
I have this 1958 Art Blakey in medium grade condition. "Moanin" is thankfully silent. Also have a 70's stereo reissue which is A+ and sounds great, but the mono without the hard L/R separation is more believable in picturing an imaginary stage with the musicians. Tonality of the instruments is about the same in both LP's.

RVG master Stereo/Mono tape(s) must be magical to experience.
