restoring a marantz 7c

[pchoi122]

hi i am helping my father restore a marantz 7c pre amp we hit a snag however, we need the original service manual or schematic in order to know the right type of potentiometer for the volume to be used, fairly certain it is a 500k potentiometer but not certain. if anyone knows where i can find more information please let me know gamerz4inc@yahoo.com

The volume pots, R24 a and b are both 500K --
Chuck Hollander and Walt Jung did a big article on Pooging the Marantz 7C in Audio Amateur February 1981 --
