So I managed to find a 19 Inch commercial tv with a promising yoke reading to swap into the 19k7000 I've been trying to match up to a CRT. It's an Orion tube from a Sansui branded TV. I hooked it all up and it lit up the fuse for a moment and then burned it open. It's the strangest thing. I checked at the usual culprits on the board and everything checked out good. Put another fuse in and it did the same. I put in a third fuse and plugged the chassis into a know good tube with an incompatible yoke and everything works fine.
Can anyone explain how a tube can fail in such a way that it will blow a fuse on a k7000.
Another thing I noticed is that the model number had the number 19 tacked on at the end instead of ending in a letter. The model in this case is A48LGS30X19. Of all of the tubes I've seen so far in the past year have all had model numbers 9 characters long ending in a letter (usually in an X).
Maybe the pin out on the tube is custom? But it did fit the cr31 socket like a glove.
