Cool man!!! What speakers were in it or did you get it unloaded?
Celestion g12 75
Definitely not stock speakers then.
How are you dating it to '72, and what does the back panel look like?
Back panel is partical board. I tried to follow this chart along with the chart on celsstions website for dating speakers. But I may have gotten thr date code wrong on the speakers apparently. I was seeing the first of the code on the speaker as EM. But I see now that could also go as dec 1995
But I am also taking all this into account of the seller saying it was an early 70s cab. but I'm not sure how he knew either.

That back panel is definitely a 70s cab and not a later reissue. It also has a 9" logo and large checkerboard, which could be as early as mid/late '72 or as late as early/mid '76. Unfortunately without the original speakers it may not be possible to narrow it down further.
Edit: I have a similar cab, but the jack panel, grillcloth, and logo have all been replaced. The speakers are original G12Hs and the other specs date it to either '77 or '78. I don't remember the date codes on the speakers; one of these years I'll have to open it and look again. Either way it sounds amazing, I just wish it wasn't so f***ing heavy :lol:
