Finally getting around to posting this,
A couple of weeks ago I picked up a Dec. 1983 JCM800 2203 from a nice guy a couple cities over. It was clean, canadian model, but the tubes are old. As such, I got a decent price on it. Managed to have it blow a fuse or two on my way to jam with Aaron, but it has since been fixed. I will be getting the full retube kit from the tube depot by the end of August for my first Sparrows show September 5th.
I don't know the year of my cab, but it is the JCM800 with G12T-65's in it, and they pair really well.
It's pretty sweet!
