What a great story ... and it only lasted thirty years from start to finish!
Seriously, it's wonderful that you found a case that matches so exactly all the control shafts and which looks gorgeous, too! Restoring and keeping that chassis for all those years earned you the "Karma" to getting such a great cabinet for it. Is this the original model which your amp came out of, or is the way everything lines up just an incredible coincidence?
Either way, well done and congratulations!
