if you can get decent rasters on all colors the CRT is not weak.
replacement those tubes. HV probs are not expensive, should be able to find one on ebay for 10-15$, very handy esp for discharging the crt (some use a grounded flat blade screw driver, but if you have the prob its just easier).
if it blooms out that is prob the ones. Have you checked the current thru the HOT? if its blooming its not being cut off but rather the HV is going away, either because the CRT is drawing too much current (incorrect CRT bias pot setting or some other defect in the drive circuits) OR the HV is simply not up to the job of providing the required current at the needed voltage.
