I can definitely see where a vastly decreased market for vacuum tubes would/could cause us to look elsewhere for vacuum tube (valves!) manufacturing than just being plain old illegal. That makes more sense. I’ve had this ridiculous notion/dream of manufacturing premium power amps and even clock/radios, stereos, etc. in the USA that used vacuum tube amplifiers just because of my passion for vacuum tube tones but the realist in me says there isn’t a market big enough to support it. How ’bout a vacuum tube iPod?
