EHX Electric Mistress Schematic Wanted

got a weird one here, early rev of the Electro Harmonix Electric Mistress,

got on this site but they do not have a schematic with four transistors, all there's have two,

http://www.metzgerralf.de/elekt/stomp/mistress/index.shtml

and the mystery chip is not on there either, looks like a Signetics 7320 which appears in no searches.

caps are ITW instead of green meanies,

transistors are 2 ea C309 and 2 ea 2N3563




thanks for any info on a schemo or the S7320!

a couple of the chips have been sanded,  here is the 7320>

ok the S7320 is a 741 opamp with the p/n sanded off and the extra transistors have base tied to emitter so they are diodes,

splicing in the changes to schematic now,

original schemo>

A different schematic of the Mistress.  Mystery IC is identified, FWIW.  Some voltages marked as well.

that's it!  where did you get that!  thganks!

idiot cj flipped the emitters thinking forward bias,

will delete bad print,

the wayback machine knows all.
