Just in time for the holidays: A bonus Truth About Vintage Amps
episode!
This week, no listener-submitted questions. Instead, we introduce
you to Joshua Dejaen, a.k.a. jdflyback on YouTube.
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!
Watch Joshua's video here: https://www.youtube.com/watch?v=-UEfqAWb3fE&t=439s
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.
Joshua has included a schematic for the spot welder he used in his
tube-making video. See the show notes on fretboardjournal.com or
check our Instagram/Patreon pages.
