OK, but consider this:I have zero attachment to guitar or guitar amp history.
Mahavishnu Orchestra released The Inner Mounting Flame in 1971, which by my reckoning was more than half a century ago, so you're simply attached to a different kind of history.

I'm not casting aspersions, so don't feel badly. Lots of the music I write might have been interesting in 1842, but probably not thereafter, and certainly not now.
By the way, I bought The Inner Mounting Flame when it came out. Great record.
At the time I was in college experiencing guitar and amp history, though at the time the stuff was new, so it wasn't history.
On the other hand, I'm well on the way to being history myself. When I go, I'm taking a tube amp.
Oh, I seriously doubt I'll get to play through it where I'm headed. I'm simply worried the place I'm going might freeze over, and I can warm myself by the tubes if there's a place to plug in.
