That's great ! Did you also kept some notes the original mic placement & conf ?
could you talk a bit more of the miking involved ?
Pretty basic mic setup with the Royer on one speaker directly on the dust cap and the 57 on another speaker about halfway between the cap and the edge of the cone. Both on axis about an inch back and carefully tested for phase. I still have the mics setup in the same position as when I captured this profile.
