I did a search, but could not find a lot of very specific info. I have been aching for a old V4 as of late, but never find them locally. Not too far from here, however, I found someone selling a V4BH that has interested me. Basically, I want to know how the two compare. What I've been looking for in a tube amp (been doing the sansamp/poweramp thing for a while now) is something I can push into nice sounding distortion without cranking so loud i drown everything out. I play in a hardcore punk band that turns up pretty loud, but we generally play smaller spaces with a PA only for vocals.
