I'm actually covered there too. I have a PVM-14L2 with a pretty damn sharp Trinitron tube but thin black lines.
I believe the Ikegamis use Panasonic tubes. Were those common in Euro TVs?
I don't know about their internals, but in-line shadow mask was the default display for most TVs, aperture grille being patented by Sony. I do believe any consumer TV with the same technology will look the same, provided they are properly tuned. The difference being the size, and the shape of the tube (flat or round, slim or full) that can influence how a picture look.
