Electronics history is very interesting. If we think that "Big Business" today is brutal, political, driven by greed and money, well, it was like that from the beginning. It was a brutal quest to be at the top of the industry. Still is that way today. People invent and see a new business. Companies have the money to invest, and make a new business rise, or never take off. Deals are made. Sounds like the Marconi situation. That name is associated with certain tubes, made by another big company, sold under many name brands, and I guess everyone wins something. All that I'm certain of is that these bottles sound GOOD.
