You mention Deraps like it matters. Who the fuck cares what a player who can cop Ed's feel thinks about what was used lol. His thoughts on the matter don't make a damn bit of difference.
Your continued almost psychotic denial of the FACTS are astounding. Because, it's very easy to explain the difference between VHI and II by adding/subtracting one thing....JBL D120s.
When it comes to power tubes, Ed mentioned long ago that he saved his supply of Sylvania/GE 6CA7s for recording since the road was eating up his tube supply. Btw, you don't have to change anything to run 6CA7s in an EL34 Marshall. Same tube with a few different sound characteristics. So he could easily just grab some Siemens 34s and throw them in for the road.
Again, have you played through JBLs? Have you played H30s? Which kinds? Cuz I have. And, there's NO WAY an H30, ANY subtype, will cop that high end sizzle that is EASILY attained with....
JBL D120s.
