In Reply to: What makes a tube with the Windmill getter structure. . . posted by John PA on February 7, 2023 at 11:41:28:
The "windmill" getter does not directly affect the audio signal or the sonic character (I assume you're referring to Raytheon origin?).
The getter structure can be a convenient visual indicator of a particular construction type and era of production.
The material purity, metallurgy, cathode coating chemistry, plate and grid alignment, getter deposition, vacuum draw, mica composition and cuts, plate shape, construction and coating, and quality control, etc. all matter to sonic performance, and can vary greatly from manufacturer to manufacturer, or between eras of production for the same manufacturer.
