Just when I thought my build was good... [fixed]

Hi,
Lastly I built a custom tone bender. When I played it straight through my amp, I was very pleased with I what heard; it sounded good (at least usefull  ) and was pretty silent, I only had a light white noise when using a low input cap.
Today I tried to put it in simple chain: wha - bender - TS-9 and clean boost.  to my big surprise not only the bender is noisy, but the TS-9 and the wah ARE way more noisier.
and that even when the tone bender is off  I'm using an AC adaptator for the Ts-9, and there is a battery in my wah (which is true bypass).
I used a Banzai 3PDT and Neutrik jack plugs. How come the pedal, being true bypass, can be the source of the noise ?? As I repeat, when it's the single pedal in the chain, it's quiet 
The bender is powered  with a battery too. What can I check ? Can someboby put me in the right direction ?
Thx for the tips,
Fabrice

Do you have another TB pedal you can put in its place, and see if the noise is coming from your build?  Or did you try adding one pedal at a time?  I'm always way too quick to suspect that the problem is stuff I made, especially something thats getting tried for the first time.  Is it a ground loop? Bad cable? Funky AC adapter?  Low battery in the Wah? The nice thing about TB is being confident that the pedal electronics are out of the equation when there is a problem with a pedal setup.

HC forumite Backstepper got it right. The input jack plug was a bit loose.
