Schematic for Early ARC 6B

Does anyone have a schematic for an early ARC 6B or one that was updated (maybe) although preamp says 6B. This peamp has the large number of power supply caps like the 6A. Thank you ver much
Check this site. The schematic is included among the photos.
Thank you. I keep getting schematics of 6b with bias pots...not on updated 6A to 6B.???
