MXR M166 Time Delay schematic anyone???

[Max]

I may have found one used with a problem on the switching part of the circuit, if anyone has a schematic of said circuit it would be really appreciated and save me the effort of tracing everything, though it shouldn't be too difficult. At least there are no smd components 
Given that I can get it at a decent price, that is, I have the feeling a lot of people is lurking just for the SAD4096...
