In part one of a series of three videos about making a replica of Brian May’s legendary Deacy amplifier, I briefly discuss the origins of the Deacy amp circuit (salvaged from a vintage transistor radio that John Deacon found in a London dumpster in 1971) and what Queen tracks Brian used it to record on. I then move on to talk about the new Knight Audio Technologies (KAT) amplifier board kit and the other component parts required including suitable vintage and modern woofer and tweeter loudspeakers and the cabinet itself. I finish by introducing the only official Deacy amplifier replica which was made by Knight Audio Technologies between 2011 and 2019.
