Tycobrahe ParaFlanger Fix, Gut Shots, and questions

[Bassmanfox]

Hey guys,
I was hoping someone would be kind enough to lend me a hand with this pedal.  I came into possession of one of these parapedals that has been mutilated by someone.  It squeaks and squawks at me with little bit of flangyness, but not much more, before i dive in I was hoping to pick someones brain about it.  Also I was able to get all the bad solder and broken traces cleaned up as nice as possible, but all the trim pots have been tweaked.  I was hoping someone has a service manual or a good idea of what they all should be set at.  This would be terrific and if anyone needs mine to use for reference I would gladly oblige.  Any info would help.  I found one schematic here http://wc6w.50webs.com/wc6wvint/index.html?fr413.html but nothing more.  Thank you ahead of time, enjoy the pix, if you want anymore let me know.
