AKB maintains correct gray scale for as long as the CRT can manage it.

My 1985 Zenith Advanced System 3 has it.RCA had it on a couple of chassis around the same time.CTC131 ,132 and 133 had it I think.Then they stopped using it until the the 178 and 179 series of the early to mid 90s.Some RCA projection sets use it.Zenith stopped using it after this chassis for a couple of years.It was used again in the Digital sets they only made a couple of years and then off and on in some chassis.None of the ones with the rotten tubes had AKB.Probably was a good thing.Philips AKB is even worse than Sony.If the G2 control in the flyback drifts or the CRT gets weak the set shuts off.The early XBR Wega flat screen chassis on Sonys would shut down if it detected an AKB error.We replaced a CRT under service contract because of this.The customer didn't seem to notice the lack of green ,just that the set shut down.Had a blue background and the highlights were mostly red. Sony must have eliminated the blanking of the picture as I just went to check a 36" Wega that the green gun was shot and it was still playing with a purple picture.
