Electro Harmonix Screaming Tree help

[stax]

Been given a broken one of the above all the components are point to point and in good shape but the battery connections are broken.
By the look of it I think the negative wire from battery snap goes to the on- off switch but not sure where the positive one goes.

Obviously it looks like the +9v is connected to the 430k and 10k resistors but this side of the resistors are connected to ground and chassis this is what I'm not understanding, sorry complete novice at this sort of thing although I have built all my pedals I have no idea really.


I don't want to have a guess in case I damage transistor.
Anyone have one of these and could help me out?
Cheers

The screaming tree is the same circuit as the screaming bird. There's a schematic here (scroll about 1/3 down):

You're right; the positive connection should go to the 430k and 10k resistors, but they shouldn't be connected to ground (except via the 43k and 390r resistors). Are you sure about your tracing? Can you post pictures?

Well the only thing connected to the input and output jack ground are 10k on input and 420k on output, no other wires.
This is the side of resistors that should be receiving the 9v+ but that seems strange to a novice as it is no different to just connecting the 9v +
to any other part of the chassis?
I'll try and work out how to post a pic.
Thanks

EH sometimes did weird things like that.  Connect your red battery lead to ground and the black lead to the switch.

Thank you, I suppose that should have been obvious really but just seemed a bit strange.
