Forgive me for not posting this sooner?
Sometimes you just gotta thank the stars (sometimes they are the only ones up late)...
I've determined that I have some rack units that were part of Phil's rack in the 80's.
I'd love to find out more about the specific connectors that were used, supply voltages, etc.
so that I might revive the two units that require special connectors and supplies.One of the units
is 110v two prong and 1/4" jacks, I used that for more than a year at home in my rack before I
knew it's origins. Crazy Mojo just sittin' there

I saw one of the units behind Jerry in a photo that was used for the Trio sessions album
with Rob Wasserman and Edie Brickel. That was an exciting moment!
I looked at many backstage photos,wall of sound pics...looking for any clues.
Maybe a month later I was on my stationary bike thumbing through the big Dead Gear book.
I saw a black rack box with three knobs in a real small picture (I'll find the page) of Phil with his rack...and I knew it was the same unit I had here now.
I've found that starting in maybe '81, until about '88...these units were a staple in Phil's rack.
Rob Wasserman or Jerry must have borrowed it for the Trio project. I also see it was used at a '91 concert with Neil Young.
I must have looked at thousands of dead photos during this 'research'. It doesn't get old...so many nice people and great times. I'll post some photos/links that have clear shots of these units in use. (Google 'Phil Lesh NASA ',or '4-30-88 Palo Alto) if you can't wait)
I've yet to open them up ( might be some service stickers ), but I bet this will be interesting to
the bunch here...and good for archiving a little bit of history.
Here's a shot of each...I'm hoping engineers here and Philheads might help me research each units history and function.
