That's correct. According to the diagram in The Making of Star Trek the "main phaser" alligns with the uppermost "ring" at the bottom of the saucer. It's a fascinating prospect that the TNG design might have originated from a mostly unvisualized idea of Matt Jefferies.
Eh. That's not what I see.
In my copy of The Making of Star Trek,
which dates from 1974, two phaser banks (both visible in the front elevation, and one visible and labeled MAIN PHASER in the port elevation) are clearly visible as two globes, resembling ball turrets
, higher up and further apart than you'd think from where the beams are normally shown coming out, but still as two very definitely fixed, localized, and globular emplacements.
