Hi all!  I've been having more trouble with mire tubescreamer clone lately.  I think I've wired the stereo jack correctly (tip is innermost lug), but I'm still having weird battery issues.  When I pull the jack from the box, there is no power whether a cable is plugged in or not, but When I secure it uninsulated to the box, the LED lights up with or without a cable in the input.  I think I may have problems with my dc jack wiring.  I'm using this metal jack from small bear, and I want to know if I'm wiring for negative ground:

So the innermost lug is board- and battery- right?  Then the second is board +, and third (outermost) is battery+?  I think I fuddled it up because I was just going by left of middle lug when the middle is facing down is battery+,etc., but my innermost lug is actually the opposite of the picture.  Any ideas?

Ok, so I think I did actually wire the dc jack correctly, but I'm confused to what is the ring tip or sleeve on a stereo jack, and which is which on the mono jack.  I see the pic in the faq, and they seem to correspond to different things than what's on the small bear site.  Ok, let me see...


and the one from this site is...

With a negative ground pedal you need to either use a plastic dc jack or isolate the dc jack from the case.  The DC jack is center negative, sleeve positive but the signal jacks carry the ground on their sleeve, so the power shorts straight to ground.

Make sure that the only wire on the ring of the input jack is the battery negative.  That makes the battery connection only active when a jack is in, but if you plug in an adapter the pedal will be on regardless.

hmm...dc jack doesn't seem to matter.  I am finding that the mono output is the one controlling the on and off of the circuit...when it's connected to the box uninsulated, that's the one that's making the battery stay on or off...what's backwards?

After checking the wiring, I decided to look at the ciruit because it was gating when engaged, but fine when bypassed...
I just checked my transistors, and something weird is going on.
If I'm not mistaken, here are the values for the 2 2n3904's:
Q1 E-3.0 B-0.25 C-9.0
Q2 E-4.5 B-0.25 C-9.0
What the heck is going on here?!!?  I'm using a cheap analog multimeter, but I believe these are right.  How are both collectors getting 9V?

With the Stereo jacks you should test to see which lugs connect to the tip ring and sleeve.  I have 2 different stereo jacks with the lugs located in different places.

Right...so the innermost stereo jack lug is the ring, and the one connected to the big metal tip is the tip, and the last one is no charge right?

Ok, found my newbie mistake (or just one of them).  Instead of using a stereo input jack, I had used a 12A mono jack (the one with the NC tip).  No wonder I couldn't easily distinguish what was what.  Looking at the jack now, It's pretty obvious what is what on the jacks.  Oh well...

Get the right parts!!!
