Hey Gear Page, wondering if you could help me with something. Right around the start of the quarantine, I was lucky enough to make a pretty killer Craigslist find. What was sold to me as a '61 "Brownface" Concert Amp. It was a killer deal, too. So far, best amp I've ever played. I hope some day soon to pickup one of those Austen Hooks projector amps and run stereo for a full Blake Mills/ Ry Cooder/ Joey Landreth kind of thing. But I'm curious - I was talking to Mr. Landreth, and he figured based on the logo and grille cloth colour it was actually a '62. It's certainly not going to make me get rid of it. I just thought it would be cool if it were a '61 as it was my Dad's birth year. Full disclosure, the cabinet is a reproduction. The original was destroyed in a flood some years ago. And it had 4 replacement speakers as opposed to the old Utah's that would have come stock. Hence the great price. Sounds killer though, so I wasn't concerned. But how would I go about dating the chassis itself? Any tips for ID'ing these old Brownface wonders? Also, anyone know what these speakers are?
