I came across some info recently that said there were 507 made. Whether or not that is true, I don’t know.

Does any one know how many black face Deluxe amps were made? I am trolling the Internet looking for that information.

the Deluxe doesn’t have a logo, the Deluxe Reverbs in that date range did.

Does the Blackface deluxe always come with no Fender logo in the upper left corner of the grill?

The AA763 circuit has a 22k resistor in the log-tail phase inverter; this was changed to 27k in the AB763. The plate resistor for the “top” side of the 12AT7 tube in the PI circuit was changed from 100k to 82k. That’s it. Otherwise, they’re identical. The change was made to tweak the phase similarity in the PI circuit, giving microscopically more headroom in the amp. Yes, you can hear it–sometimes–when playing at specific volumes and with a limited amount of surrounding noise. In a band setting at volumes this amp is normally used at, you can’t hear the difference. (The change was actually made to clean up the PI circuit in other amps, as part of the general AB763 overhaul. You can hear the change a bit better on the 6L6GC amps, such as the Pro . Also note that this change was generally made to amps that use a simple 820 ohm resistor int he negative feedback loop. Strictly speaking, the AB763 PI circuit is probably the “standard blackface” version. The AA763 version is a carry-over from the late tweed/brownface/blonde eras.
