I would have seen the cap off but the 6BK4 is very well hidden behind a hinged high voltage cage. In order to get to it the cage is pulled back and the tube is then visible. The 6C4 pincushion tube is even harder to get to.
This has been a fun set to keep going. It was someones daily driver for many years then it sat in a house flooded by Katrina. It didn't get wet but it sat in a swamp like envirionment for a few weeks until the owners came home.
Just imagine reaching over to get the 6C4 out and having the 6BK4 take a bite out of you (no HV bleeders on this critter)!

I said what I said about HV arcing only because you had mentioned "what a racket!" when the set was powered on. If it only arced for a second or so, however, that arc must have been quite loud.
I'm amazed that TV
didn't get wet during the floods from Katrina. If the set was in a room that was flooded, I would expect the TV to be affected -- at least the cabinet would have been soaked, at least partially, and the finish damaged. Because the set sat in a "swamp-like" environment for several weeks, however, there could have been damage to the flyback and other parts of the HV system from high humidity. I suspect the one-second arc you heard may have been the flyback windings shorting to the core, although if this were the case the short would be permanent and should have blown the fuse in the cage. If the set works now and hasn't arced since, however, I don't know what could have caused the arc -- could have been any one of a dozen things.
