Celebrating 50 Years

Penta Laboratories was founded in 1951, and is celebrating our 50 year anniversary this year. In honor of our celebration, I thought that I'd post some information about Penta Labs electron tubes through the ages. Below is a catalog page from 1961.

This was the same year that:

• John F. Kennedy delivered the first live presidential news conference



• Yuri Gagarin became the first human in space



• Roger Maris hits 61 home runs to break Babe Ruth's single season home run record



• The Fantastic Four Comic Book Series debuts



• The Ken doll is introduced



• And Penta perfected our beam-power Pentode vacuum tube
