Instead, we introduce you to Joshua Dejaen, a.k.a. jdflyback on YouTube.</p> <p>This young, Pacific Northwest-based electrical engineer has taken YouTube by storm with a viral video where he not only built a tube amp from scratch, he even built the tubes!<br /> <br /> Watch Joshua's video here: <a href= "https://www.youtube.com/watch?v=-UEfqAWb3fE&t=439s">https://www.youtube.com/watch?v=-UEfqAWb3fE&t=439s</a></p> <p>During our chat, we hear how Joshua got his start building vacuum tubes at home, learn about some of the grassroots tube builders / electrical engineers who have inspired him along the way, and hear about Joshua's build process. We also learn about the perils of microwave oven transformers and so much more.<br /> <br /> Joshua has included a schematic for the spot welder he used in his tube-making video.
