Pre-gain filtering, cathodyne phase inverters, and big, clean power sections.
What exactly is a cathodyne phase inverter?
A cathodyne is a PI that only uses one triode, as opposed to the "standard" long-tailed pair PI that most amps use. With a cathodyne, you're basically using the triode as a regular preamp gain stage (inverting) with a gain of one AND a cathode follower (non-inverting) at the same time. With a LTP, you're using two triodes - one makes the inverting signal, one makes the non-inverting signal.
The advantage of a cathodyne is that it's a lot cleaner than an LTP, but the LTP sounds better when it clips (as evidenced by any Marshall recording, ever). But, if you're designing an amp around a clean power section, you want to make sure that the PI isn't clipping anyway. Also, since you're only using half of the triode, you can use the remaining gain stage to do something awesome...like add more gain.

You guys can "pick apart" little stuff like transformers, bat rays, and flux capaciters, but the signature VHT sound that consists of a very dry, clean, super tight gain comes a lot from their cabs. I haven't had a 1/2 dozen of their heads, but I have had two AND the matching fatbottom cab.
Every head I tried on my fatbottom cab immediately took on some of those characteristics, with obviously a Pittbull head on top making it sound correct.
I use my CLX head with my Diezel german made cab, and it sounds pretty darned close to the Herbert through the same cab.
That's funny - I played my UL through a Behringer cab once, and it totally did NOT catch on fire.
It also sounded like an UltraLead, but Behringer is known less for their tone and more for their combustion.
