Re: [ARSCLIST] playback curves for some 78s

I'm wondering about what's a good playback curve (turnover and rolloff settings) for:
1. the Columbia reissue Bix and Tram disks, albums were put out in the late 1940s. If these are just re-pressings from the original Okeh metal parts, then they need the original Okeh early-electric playback characteristics, right?

Usually you can tell if they are original master pressings by looking at
the lead-out grooving and the matrix numbers. Columbia often grafted a
new style lead out on top of the original lead out, creating a very
complicated looking mess. Some of these Columbia reissue sets were
original masters in their earlier pressings and then got dubbed masters
when the original metals wore out.

But if they are disk-to-disk transfers, I'm thinking they'd be the 1940's Columbia curve, no?

No, because it would also be affected by the curve Columbia would have used to play the original discs. Of course you could just ask George Avakian and see if he remembers what the engineers did. Anybody got his email address? He used to come to the NJ Jazz Bash that is coming up next month.

By the way, the current ARSC Journal has Gary Gallo's definitive article
on the Columbia LP curve and its relationship to the NAB curve for ETs.

Reissues of original Columbia or Okeh records from the 1925-3? era are
VERY commonly dubs...since the originals were 10.25" discs and the
stampers don't fit onto modern-day 10" records...!
