It could be a 72. I am old, after all. Definately not a 73, or later, as I know where I was and there is know way I could have gotten the amp past 72. I'll check it tonight. Not really interested in using that head. Yeah, its a combo. I have replaced the speaker on a few occasions, and a couple of tubes (harder to find those these days, so it may be on its last legs).
But the dang thing has a nice warm, clean sound to it. Really going to miss it when it finally dies.
I have a pic of all my stuff somewhere. I'll see if I can dig it up.
