[EDIT] Duo-Phase LFO B CONSTANT LED

EDIT : i tried to unmount few resistors to check their values and i have now a constant led on LFO B and the sync with LFO A does not work anymore.

Hello to the community.

I am having a problem on a recently built DuoPhase and I would be incredibly grateful if someone could help me find a solution.

The behavior of phaser B when activated alone is different from the behavior of phaser A.
It seems like there's a problem with phaser B’s LFO :
The "Rate" knob of B goes much faster than A (around same speed on B at 9 o’clock than clockwise on A).
And the modulation of the sound is much shallower compared to A.

On the other hand, when the "Sync" switch is activated, phaser B behaves normally and follows the rate of A with the same modulation amplitude as phaser A.


I'm getting desperate with this build, i'd really appreciate if anyone could give me a hand on this.

Thanks !
