I found some JHS Sylvania 5751's with gold writing and grey plates. No gold pins, and these have square, not round getters. I thought the JHS tubes were black plate. Can someone clarify this for me?

Also, these a triple plate but are there ones like this that aren't triple plate (double plate)? Whats the difference in sound?
Is this the same tube as the gold brand gold pin grey plate sylvania 5751 (see link below) but without the gold plating on the pins?
