AB763 stripped down?
Posted: Sun Dec 27, 2009 11:16 am
has anybody here ever stripped down a Fender Showman or Twin, AB763 circuit, to get rid of the vibrato circuit? i am wanting to step up into a bit higher wattage amp (i'll still keep my 50 watter for backup thanks!) but i don't want to go so high as to have to respeaker my cab (a mid 60's dual cell blonde Bassman 212) which is presently loaded with G12t-75's parallel for a total of 150 watts, 8 ohms. 80 to 100 watts rms would be fine. if i would have to respeaker i can but i really like the tone. just want some more balls (short for ballistics). maybe another cab wiffem a 15 incher?
another thought would be to step up the OT in the same power out circuit to help prevent saturation and help keep it clean and strong with the bass response. presently the curcuit calls for a 022889 (new Fender number replacing the old 125A30A number).
the triode stock OT replacement or magnetics components number is 40-18013 for the 022889 tranny. i was thinking a Hammond 1650T might do the trick for about 100 to 120 watts. any suggestions or opinions? the idea is to get more clean bass headroom without a lot of overkill.
basically this is the idea:
