Don’t confuse power consumption wattage with speaker output wattage.Consumption numbers are near the convience a/c outlet and are with the 120v-60hz lable.The speaker wattage is under the left side speaker jack.

AA864 Bassman was switched to the AA165 in January of 1965 until about mid-March give or take a week. Almost every AA165 Bassman has a tube chart inside the back of the cabinet that shows the AA864 circuit. After March at some point the AB165 circuit was manufactured and most of the early AB165 amps actually show the AA165 tube chart. Very confusing. To my knowledge (research) no AA165 amps exist with true AA165 tube charts. Has anyone ever seen an AA165 Bassman with an original AA165 tube chart?

CBS did not put any workers or amp designers in place until a few years after Jan 5, 1965 so all intents and purposes these circuits were not CBS.

Fender was fully owned by CBS in 65, 64 was their transition year, company was sold January 5th 1965 but the transition logo was used in 1964 because plans for the sale had already begun. So unless an amp was built and finished in less than 4 days there are 0 pre-CBS 1965 fender amps.
