Great Vintage Vacuum retailer Tube. Large Rare Part for Steampunk and Maker Crafting. Sylvanian Model CHS 811. Tested Good for Continuity.

We've already had some fun with vintage vacuum tubes and we're rapidly selling out of them. Great crafting material. This one is outstanding - especially considering it's size! In good condition with clear, bright glass. Tested good for continuity only; as-is. Some darkening of the glass on one side (see photos). Sylvania make; model CHS 811. Fun for crafting, radio design, etc. We will include the retailer original porcelain socket base with 2 alloy elevating spacers as photographed. We used a smaller similar tube for a fun H.G. Wells inspired design - see final photo or follow this link to the listing:
