Fitz's posts on modding the Darkvoice 336 are well worth a read. I'm curious if anyone has modded the DV332.

 

In particular, I'm curious whether anyone has determined what's going on with global negative feedback in the DV332. The lack of a very great difference in sound when tuberolling as compared to other amps I've owned leads me to believe that there's gobs of GNF in the 332. I could, of course, be wrong about that.  Does anyone know? If there is lots of GNF, it would do wonders to the amp, IMO, to do away with it, as long as the amp's layout doesn't then generate an unpalatable hum.
