Hello, fellow Audiophiles.  Drew found a video that he thought you might enjoy.  It explains how audio tubes are constructed.  Happy listening and learning.  Give us a comment here on the blog and let us know how you liked it and any questions you might have for Drew.  Best one this week wins a $25 gift card.  Easy, huh?  :)
