7jp4 tube is it bad?

[fumplet]

well it did work so did I just bump the vertical height knob and all is well or can these tubes short and start shrinking the bottom and top of the raster so it has like just under 3 inches of raster bottom to top? Its not quite as bright as my Early Television Museum 7jp4 but its good. Dont think I will ever get a tube that good again. No raster on the 7vt5r chassis but experience from my first set tells me it needs a recap as I didnt get raster on the 1st chassis either until some caps were replaced.
