Hi Paul
I've had a couple 19LZ sets pass through my hands, and still own a 91RX (same cabinet). I can verify that all four grilles should definitely be open.
Just looked at your 19LZ page - very nice! The 19LZ Joe is restoring is one I sold to him recently. It, too, has a four-point tone control. My guess is that Philco made this change very early on, or perhaps the 19 always had a four point tone control but it just wasn't documented? Joe's 19LZ is a Code 122, I believe (AM only). It has the AC socket in back, as does yours. Philco documentation mentions that this socket was removed later in production.
