I thought he did a great job figuring this out with no real previous experience in this sort of design. That case is tiny and I think Mr. Gatekeeper is a big boy like me!

100 watts from a MRF455A is not bad at all. That get's you your first major jump in performance at 100w mark!

That is how I get 200 watts rms easy all day every day from an MRF454. Not my design though I just populate the board that Brian designed!

  • @ Hambones amps:
    Does anyone know if you can replace the 2290 in a galaxy dx 93t twin turbine with a 2sc2879 red dot? If so, what would have to be tuned?
  • @ ShadowDelaware:
    Hambones the entire amp section would have to be retuned, and the rf transformers re wrapped.
