Electro Harmonix Screaming Tree help

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.

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 batterys minus connector goes to the input jack where it will be switched to the negative ground when you insert the plug.The batterys plus connector should be soldered to the point where the 430 k and the 10 k resistor meet and nowhere else.Are you sure that you´re not confusing the 43 k and the 430 k colour code? It is easy to do.

Thanks but I got the answer over at diy stomp boxes, the negative wire from battery did go to on-off switch (on these pedals both jacks are mono) the live side of the 10K and 420k is connected to the ground terminal on the jacks 10k on input and 420K on output this is these are the only things connected to jacks, the +9v is connected to ground, I know it sounds strange and that is what was throwing me.
I've attached pic so you can see.

Or as the short but helpful answer on DIY stompboxes put it.

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

Did anyone at DIY bother to explain why? Old EH and many other old pedals, like the Fuzz Face, were often PNP transistors and therefore positive ground. Modern pedals mostly use NPN transistors which are negative ground. Don't be surprised if your Tree don't work well with ALL your other effects... sometimes the positive ground interacts weird... depends on the other pedal having a buffer or not, among other things...

Just as a heads up you could swap input cap values and turn that into a (much more useable IMO) LPB-1. Then again maybe I just heard a bad one, but it sounded very icepicky and piercing.

Hey guys im building one of these from scratch right now and i have been having some issues with it actually working.... i am just making one with a DPDT switch no on/off and a stomp switch i was just confused... does any have a point to point diagram for this? or at least any pointers or tips???? as i am a super NOOB when it comes to electronics as well...
THANKS!!!

The only thing I am sure of right now, is that the schematic on top of this page (from fuzz central) describes a Screaming Tree with a silicon NPN transistor as opposed to the one at diy which obviously is a version with a germanium PNP transistor.The giveaway is of course "+9v is connected to ground"
Well,it is getting late here in Sweden (9:30) so I should begin to unwind.
Good Night!

Well I think with the diagram and the pic it just about says it all it is so simple the only thing that could go wrong was the orientation of the transistor especially as there seems to be different types NPN PNP as in limbe's post.
Just for the record I didn't find it to be that useful as it is so may do LPB-1 mod Brandon Cur mentioned.

well i just dont know what lugs to actually attach what do on the switch as to this one you're showing me in the picture has a 3 lug foot switch and a 2 lug on off... im just kinda clueless on this kinda thing :P

If you do the "LPB-1 mod" and change the capacitor to 0.1 µF you´re actually just restoring the screaming bird to the LPB-1 which was the daddy to all the others.The LPB (Linear Power Booster) was useful when it hit the market because the amplifiers had so much headroom and many pickups had low outputs.This led to claims in the ads that you could make your guitar sound ten times bigger.Don´t get too disappointed if your LPB doesn´t meet your expectations since today we have amplifiers with high gains and pickups with high outputs.

Hi Berndizzle440! If you go to www.beavisaudio.com/techpages/HIW/hiw1.gif Beavis will explain what every part in a LPB-1 Booster does. I find it very informative.
Thanks for taking your time to dissect a single transistor common emitter preamp Beavis!

I'd be thinking that's what you'd expect from a treble booster.
