FDP Forum / Fender Amps: Vintage (before 1985) / Can someone identify which circuit this is

Can someone identify which circuit this 68 Silverfave Twin Reverb has. There were a few different ones I think. The tube chart says AB763 but this isn't a Blackface circuit, I’m familiar with these. I’d lke to find the right schematic for this amp. I believe this is one of those CBS brainchild circuits.

68 SF Twin Reverb Circuit?

Thank you for that link. I believe you could be right it looks like the Twin Reverb AC568 layout. Mow for some fun.

Those big rectangle precision resisters on the cathodes of the 6L6's tells me it is not AB763. It is one of the '68 circuits. I have a Twin exactly like this. Still is a great amp.
