I had one of those Westinghouse 19" BW sets, a 1963 attache' model, that was instant on.
I also have a 19" Westinghouse color, 1968 model, also instant on AND has a defeat switch on the back, like your RCA, that "unhooks" rectiifer diode mentioned below.
There is a two-gang on-off switch. One side switches power to the solid-state LV rectifiers, the other side had a rectifier diode across it and switches the series-wired heater string (and CRT filament transformer on the color set) such that when the set was off, only 1/2 cycle of AC is applied to tube heaters, keeping them kind of hot and significantly reducing warm-up time.
BTW - I removed this feature on both sets.
