Jerry Garcia’s McIntosh amp


Does anyone know what model McIntosh amp it was that Jerry used when he played live onstage?  He sure seemed fond of it and I might like to play my guitar thru one as well.  Thx,  Gordon

@He’s my pride and joy.  I was so sad after the real Jerry died in ‘95 that it took me about 20 years until I was ready to listen to the bands many live shows on the RELISTEN app and on YouTube.  My Grateful Dead years were ‘87-‘93 and I had the pleasure of seeing 21 live shows.  I wish I had made it to more.  I know 21 isn’t many in the GD community but I was a starving student at the time.  I did have the pleasure of seeing their Halloween show in London in 1990 when some friends had an extra ticket and asked me to join them at the last minute... and I had just gotten my first passport for a work opportunity on the Marshall Islands that fell thru.  What a long strange trip it’s been :)
@doug714 and all - Many thanks for the GD knowledge transfer, and thanks for the RELISTEN tip - I wasn't aware of it - looks like I have a whole new music source to now dig through...Thanks! 
@acefactory Almost Every Grateful Dead show is there. Most have many different tapers recordings so you can browse thru and pick the best recording to listen to. More that 10,000 recordings from their 2000+ live shows. Dig in and enjoy,  1977 was a great year for them so I suggest you start there. 
Great post! SOmeone should make a full length documentary about the Wall of Sound, legendary as it is. In the meantime, found and thought i would share this:
