Highly sought after AA864 circuit in good working condition. Looking to swap for a Marshall 4x12 and tube head 100W or louder. My Champ is also on the chopping block. Production line stamped #1 on tube chart. New and nicely broken in Jensen C8R installed. Comes with a 1966 C8R in need of a small cone repair. Jcm 800, Jcm 2000, 5150, 6505, V4 etc... willing to throw in cash depending on what you've got.
