wiring question and loading problem multiple effects in one box

[tomnottom]

I have wired 2 effects in a single box using the same power supply using the wiring diagram in this post. I added a fuzz face (end of chain, NPN silicone) following the same diagram and it sounds like the whole thing is loaded down (not sure if the term is correct). When I have the FF on its own power and by itself it sounds great after the box with the two effects in one box. Can I  share a 9 volt power supply with the 3 effects in one box? The effects are green ringer(clone)> Bsiab2 low gain> fuzz face(clone) all with LEDs. Thanks in advance

Please help

What is the current capability of the power suppy, and how much current is each of the effects drawing?

[tomnottom]

Nine volt power supply

FF =
Q1 c4.5 b.5 e.0 
Q2 c4.5 b1.4 e.8

BSIAB2=
Q1 .0 .95 4.5
Q2 8.5 4.5 3.8
Q3 .3 .75 4.3
Q4 8.0 4.3 3.8
Q5 .5 .9 3.4

green ringer=

Q1   5.5 1.8 1.1
Q2   2.6 5.5 6.2
Q3  8.8 4.0 3.4

I hope I am answering the question.

I can get it to work with 2 effects in the box but he 3rd effect changes the whole project.

These are all voltages. What you need to check is the current consumption of each device. It should be measured in mA (or millamps). There should also be a current rating on the power supply itself, either in mA or A (amps). Your problem could be the result of the power supply not being able to source enough current to power all the effects. Can you change the order of the effects? IOW, can you try hooking up just the Green Ringer and the FuzzFace and see how that works?

At the office so when I get home I will check this out. I have tried running just 2 in it with the power supply I have (visual sound) with each combo FF+BSIAB, BSIAB+ GR, FF+GR and that works. If the issue is a  "result of the power supply not being able to source enough current to power all the effects". What do I do? I hate being the new guy with all of the great questions.

Thanks Tom

  They're all low current draw, the PS can be tested against a 9v battery.
  If all the circuits are NPN/Negative Gnd., the power supply can be connected to all three.
