    I Built A Guitar Amplifier From Scratch

    I’ve been studying the art of tube amplifier design for about ten years now, and actually repairing them for about five. I love analizing schematics, pouring over the inside of an amp chassis, and studying the layout choices made by the designer. It was only a matter of time before I took a crack at it myself. That time finally came.

    Phantom Crackle

    My buddy Ivan uses this combo-ified 1963 Band-Master as his backup. It suffered from a phantom crackle that would only appear after being warmed up for an hour or two. It had been in and out of another shop for over a year, and the problem was never successfully addressed.

    Sliver-Face Champ

    About three or four years ago, I found myself falling down a rabbit hole of tube amp repair videos. It started innocently enough with the humble idea of building a custom foot-switchable preamp/mixer for my double bass. That lead to me building a few guitar stomp boxes. Before I knew it, I was watching hours and hours of tube amp repair videos every week.
