Ampeg J-12-? schematic

[Merriam Shoals]

Thanks Hangman! That looks close pre and power tube-wise. My J-12-T has a 5Y3 rectifier tube and this "D" schematic looks like it has a solid state rectifier. I also have a 1966 J-12-D so this might come in handy some day. I appreciate your help on this... I think I am just going to have my local tech work on the J-12-T for me. (it has developed a slight hum) He probably can figure it out. On another topic, what is your take on the 3 foot pegs vs 4 foot pegs? My J-12-T has 3 footpegs, and the J-12-D has 4. Do you think Ampeg thought that the odd number of footpegs would help the cabinet resonate better?
