I totally am a believer that the construction of a tube determines how it will sound. This makes perfect sense when you consider the tube is relies on the changing flux of electrons in a vacuum. It is easier at least for me to visualize this as a physical event affected by physical construction and vibration than the electromagnetic field pulses in wires. Now that have begun to pay attention to that sort of thing, I can almost predict how a tube will sound based on how it is constructed and how it resonates when tapped.
At any rate, I have tried some NOS 2A3 tubes but not the exact ones you describe, at least they do not look the way you describe them. If you have some photos that may help. I will look around for some of those spring-top Sylvanias and post my results if I get some.
