Jerry Garcia’s McIntosh amp

I watched the WoS being setup once and there were 3 tall/huge McIntosh tube amplifiers positioned center stage.

Two were close together (same cabinet I think) and the other was maybe 4'-5' away.

Not a clue as to what they were powering.

I attended the concert that weekend, but stayed way back because I forgot my earplugs.

This was @ the Iowa State Fairgrounds around 72-74.

I used to know the model #, but no longer remember it.

Y’all sound like you may already know but there’s a great book called Grateful Dead Gear (with lots of photos) that chronicles everyone’s rigs and their changes. 

Thanks jriggy.  I will certainly check it out.  I really appreciate it :)

My reference is late 60`-70`s. I helped with their sound at about 100 concerts during this period. In the beginning Jerry was very picky about his equipment guitars were custom made except the one from Gram Nash. During the late 70`s that seemed to have changed somewhat, on more than one occasion on stage he would plug into someone else`s amp knowing or not knowing we never asked. What was done in the 80`s i do not know.
