OK - doesn't sound like it's braids or the PH osc then!
what happens if you only connect braids to the mixer and then to the output module?
what happens if you connect both modules to the mixer but into different inputs??
do you have other sound sources you could try with the mixer, maybe a friend has one if you don't?
do you have another mixer you could try with the sound sources, again maybe a friend has one if you don't?
have you tried changing the power header that the mixer is plugged into??

Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
