The jitters look like it could have a bad Mica cap in the Horizontal.

As for washing out it may just be you're turning up the brightness too far since it looks okay otherwise, the white lines are retrace lines, often caused by running the brightness too high, though a weak CRT can aggravate the problem.

I don't see any blooming, blooming is when the entire picture gets larger and dimmer as you turn up the brightness, often caused by a bad HV rectifier tube, your raster stays the same size even with the brightness cranked up, that's generally a sign of a healthy high voltage supply.
