Just had a quick look through the Carnt and Townsend reference. They say there's a great advantage to +ve mod with AM sound but I can't really see how that conclusion can be drawn from the evidence they present. Yes, +ve has advantages but so does -ve. The question of gated AGC is interesting. AFAIK it was little used in the UK in single standard 625 sets. For that matter it wasn't much used for 405 with "Always Grey Control" results. I don't know about US practice.
