Found this channel through a discussion on Reddit about restoring old radios.
I’m still only marginally electronics-knowledgeable: I got my ham license last year, but I’ve only used it once, and my barely-used Arduino and Pi were stolen last year when my house was burgled.
But, I’m definitely looking forward to watching more of this video. Not sure at 2 hours I’ll make it all the way through, but he knows his stuff, knows how to present it, and this is my first exposure to vacuum tubes.
