Bad CRT on my WS-65611 P/N 251C220050

I just had my WS-65611 convergance problem repaired $550 and after it ran for a day my wife asked ab out a red hue on the left side of screen. I asked the repair guys to come back over and adjust. They stated that the red CRT was damadged (I saw a spot on the crt damaged) they stated they had not messed with that but I have never seen this before. I guess I need a CRT but cannot seem to find one anybody got a clue where I can find one?
