Anyone tried or have ideas on how converting my TRIWATT w/ a no negative feedback pot that I could dial in and out? I did this to my Allen Accomplice, which is fixed bias too at about the same power rating, with good results. Amp does not get unstable/oscillations, etc.

I have never heard if this being done with any kind of Hiwatt or Hiwatt variant, such as the Triwatt. The way the NFB and presence circuit works in a Hiwatt is very different to how it is in Fender/Marshall derivatives, such as the Allen. The whole Hiwatt design is finely tuned and balanced, since Dave Reeeves who designed them, was a very clever engineer and not just a circuit hacker, like most other amp designers out there. Bottom line, I don't think there is *any* benefit to be had from trying this, apart from as a purely experimental, learning exercise.
