Is this CTC-16F flyback a goner?

[Ralph S]

Hi: I had this CTC-16F on for about 2 hours when the HV went off and smoke started coming out of the cage. After things cooled off, I opened it up and thought I saw a small spider running out but I could be wrong. In any case if you look at the attached pictures you'll seek what look like carbon covered web-like threads on the floor and walls of the cage. What do you think is the real cause for the failure: a spider web, failed component(s) or an old flyback giving up the ghost? Is this flyback repairable?
