I made a post about this earlier but didn't get any answers. So I've been seriously looking at these two options from Vox's somewhat new Heritage collection (either the AC30HH and the matching cab or the AC30H2 2x12 Combo). I'd much rather have the combo as far as ease of transport goes, but I've heard that Vox's combos are notorious for drastically shortening the lives of tubes...the speakers rumble the tube housing/circuit, and whammo. Apparently, this does not occur as often with the Head/Cab version. Anyone have any insights? Thanks in advance!
