A quick call and the tech was professional and courteous but was unable to name exactly where the glass is made for this series other than who ever gets the contract. He went on to name several countries, including china, and Scotland! I pressed a little bit but his response was well practiced and so I continue to sniff around for a tube minus china glass/parts. Just some food for thought. Although, the Scotland thing has me looking at a single malt bottle on my shelf even though it's a school night...
