Greetings,
On my pre-CBS Blackface Deluxe, the tube chart sticker says the circuit is AB763.
It was made March of 1965 according to the “OC” date stamp on the sticker. (‘O’ is ’65, ‘C’ is March.)
You have these listed as AA763. Can anyone tell me the difference between these two circuits?
Thanks (:
Look on the back panel it’ll say Columbia musical instruments back there! if its pre-CBS it wont,,you’re 65 isn’t!!!
There is really no difference, except for the cathode resistor on stage 2 of the Vibrato circuit. It has been mentioned that some values on the phase inverter were changed, but that depends on the actual model, and not the circuit number used across all models. In other words, you will find AA schematics with either choice of phase inverter values. Same goes for the AB schematics.
Correct!! My ’65 blackface deluxe also has circuit AB763
Also, how many watts? Anyone ?
22 watts
Hi! there is anyone that could give me details (or pictures) about speakers and the switch of a fender deluxe amp 1966 please? I’m going to buy one but I’m not sure if it is all original! cheers
Mine is a ’65 and makes 22w. Original speaker was an Oxford.
Also the tube chart states the circuit is AB763 rather than AA763. No idea what the difference is!
Slightly later version!
A few pics. The Celestion G12-H is obviously non-original, I took the Oxford out and retired it.
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.
anyone know of an aftermarket cabinet maker? I want to put my ’64 in another cab and keep my original in wraps.
thx
Hi! Yes, you should check out http://www.mojotone.com – they make a great reproduction cabinets!
That is a totally smart idea.
jabguit, Don’t know if you have a replacement cabinet for you amp as of yet. But we would be happy to build one for you. Dutch https://www.facebook.com/Vin-Tone-247105618679894/
Does the Blackface deluxe always come with no Fender logo in the upper left corner of the grill?
That Blackface should come with the underlining tail Fender logo.
Correction, the Deluxe doesn’t have a logo, the Deluxe Reverbs in that date range did.
Hello at All, and thanks it is very very good info and hep for my.
My real name is Jose an my nick name in all forums is fmk, i write of SPAIN-(Madrid)

I have a deluxe with a metal fender logo in upper left corner of grill. Black face with white lettering saying deluxe -amp
I have a deluxe with a metal fender logo in the upper left corner. In white lettering on the black face it says deluxe-amp. Not sure the year but, I know it’s mid 60’s. It has tremolo
Mine is from April 1964 (date stamp says ND), and it has the logo on the left upper corner too. Exceptions are there to prove the rule ;-D Also, mine has a Deluxe Reverb tube chart in it by mistake, and someone removed the portion showing the 2 extra preamp tubes.
Does any one know how many black face Deluxe amps were made? I am trolling the Internet looking for that information.
I came across some info recently that said there were 507 made. Whether or not that is true, I don’t know.
my deluxe is 63 by tube chart!
but,,,it allso claims CBS on the back panel!
CBS was in the mix by late 63!
sooooooo,bring on the arguements about your 65 pre CBS amps##
Look on the back panel it’ll say Columbia musical instruments back there! if its pre-CBS it wont,,you’re 65 isn’t!!!
