  OK Got it... you used the IRF 9530. My bad. How did it go? I sell a bunch of the KL203. It is a good little amp for 80-100w out. Seems to handle 20w drive with no issues. I just keep RM3's and spare boards on hand.

  Did you really replace the little RM3 Mosfets in a KL203 with the larger EKL 9530 mosfet?
  Any pictures? Surprised you found enough room. Be an interesting amplifier! Did you need to change any other components?
