If you crank the AGC from min to max you should go from blank raster to weak contrast to strong contrast to wildly excessive contrast/loss of synch to negative video and or useless chaos on screen. If you don't have that then the AGC circuit is not properly functioning.
More contrast should not wash out the picture, less should. More should make the darks darker relative to the brights areas. The brightness control should normally be able to washout the image when maxed out. Have you ever put that test CRT you're using through a proper CRT test using a CRT tester? If it is in bad shape it could be contributing to things.
