I was wondering if anyone had some insight into the electrical principle that's used in the GT ViPre rise time control. I haven't seen a schematic - I doubt I ever will. I was originally thinking that this might be just a variable global negative feedback control. But, from the block diagram, it looks like it controls something entirely in the 2nd differential gain stage. Has anyone seen the inside of one of these boxes who would be able to shed some light?
