My Research Of the Circuitry Indicates this is a Blackface AB763 Circuit:
Blue Molded Plastic Capacitors - Flanking the edges of the board are the distinctive blue cylindrical signal/coupling capacitors. These molded components are highly valued by collectors for their specific warm tonal profile and are synonymous with original Blackface-era production. CBS-era Silverface models quickly replaced these with brown "turds" or blue/orange drop capacitors. [1, 2]
Cloth-Covered Push-Back Wiring - The point-to-point connections feature traditional yellow and multi-colored cloth-covered wire. Later Silverface amplifiers shifted production toward stiffer, cheaper plastic-coated hookup wire, changing the internal aesthetic of the chassis.
Absence of Silverface Parasitic Suppression - If this were a standard late-60s or 1970s Silverface circuit, you would typically see messy additions like ceramic capacitors soldered directly onto the power tube sockets to suppress parasitic oscillation, along with massive ceramic cathode resistors running to ground. This layout is completely clean and follows the legendary Leo Fender-era layout blueprint.
