Penta maintains an inventory of rare and "vintage" tubes. The oldest one in stock fits applications dating back to 1910.

That means that the uses for these tubes were created the same year that:

• Halley's Comet was seen.
• The Union of South Africa was created.
• The first commerical freight air flight took place.
• Henry Ford was setting records by selling 10,000 automobiles.
• Mother Teresa was born.
