I need some help with an 88 MXR Phase 90

[sevenisthenumber]

I cant seem to find what Im looking for. I have an 88 phase 90 with the small old style pcb. Ive done this on the newer ones but Im having  hard time finding the mod componenets due to the fact that their not labeled.
I want to do these mods but none of the components are labeled on the board:

1) True bypass
2) faster available speed
3) Univibe Mod
4) Switchable R28 Script Mod (remove RC8 and C11 totally)
5) Add a depth control on R28 by having a 50k pot as a variable resistor

Just compare it with schematics, it should be pretty easy.. btw. 24k resistors are used instead of 22k in your piece..

..and I'd say it's "script" circuitry, check here: http://www.erikhansen.net/?page_id=32 - vintage block logo with a block logo board (dual opamps)

Sorry, I was bit in rush when posting this one, please ignore this post or at least the part about the "script" circuitry, it probably is not true.
