General Information
Minute’s 45 amplifier comes from SAC Thailand, a small boutique audio manufacturer based in Thailand, famous for making world-class output transformers and transformer based volume controls. The Minute 45 is a custom build amp based on the Minute 300B (with the 300B tubes), so you’re not going to find it listed in SAC’s website. If you wish to, SAC can build you an amplifier that will accommodate both the 45 and the 300B tube (you only have to flick a switch to choose the tube to use), but according to them, best sound is achieved when you dedicate the design solely to one tube type, so this build is strictly a 45 tube amplifier.
