In the next few days I post up bits for the new mini A/B 70W power Amp based on the M100 design but less. I have made the kit cheap to produce but you will need to have steady hands The 3 PCB will be about £90 a set, in the set you get two amp PCB and one split psu capacitor pcb. With the the correct set up there will be a multitude of possible configuration. From a Push Pull 15W A Class to 150 Mono Bridge Disco monster. You can have either FET or Transistor outputs your choice. All you need to get is a chassis, heat sinks, transformer, terminal and components plus odd sundries.
All what you need will be on Chews and with more info for the brave on my SECA page.
