Eventide PS101 Instant Phaser

[tardishead]

Hi there
Does anyone have a schematic for the Instant Phaser. I have searched on this forum and the schematics posted don't match mine.
Different opamps and other components.
My problem I think lies around the first input opamp. My main problem is that I can't identify the value of the cap in between pins 2 and 6 on the first 301 opamp. Most similar schematics say 300pf but the cap on mine says 68. Picofarads I presume does that sound right??

It's probably there to ensure stability, if the stage doesn't get into oscillation with 68pF you should be right, you won't hear the oscillation but an exagerated DC offset may appear on the output of the stage or too much distortion. Best way to be sure is to use an oscilloscope and check.
