Milenium II Bypass LED problem

[Ricardo Antunes]

Hy friends!!!
What´s happening here with my bypass LED? When the effect is off, after some minutes the LED turn on again (just a little less bright). In my Small Stone,  just some seconds after I stomp turning off the effect, the LED begins to pulse (according the LFO pulses rate ?).
I used BST72A MOSFET for substituting the original BS170 (I didn´t found it in Brazil).
Can you help me, please?

Thanks

Most times a bypass didn't worked I simply burned the Mosfet. It is very(!) sensitive to static electricity, though.

what did you use for the low-leakage diode?
Just thinkin' out loud here...
