Angus Young's amp rig

[EL34]

How many 100 watt Marshall's does it take?

So, based on his description of the dial settings -- low volume on the preamp, low TMB values, biasing the power tubes "by ear" and then adding some more -- seems like he is basing his tone primarily on EL-34 distortion.   Is that so?
