Hey y'all,
I built the Harbinger in summer of 2014 and I've absolutely loved it. A few months ago, the effect stopped working.
It was like the effect got weaker and weaker. The pulsing didn't seem as deep, and eventually, it just stopped.
There's a signal in bypass mode, and there's a signal when the effect is engaged. I opened up the unit and saw that the mini lightbulb wasn't blinking anymore although the rate LED still blinks.
Here's what I've done so far:
1) Reflowed all the joints and connections (and double checked the connection at the speed pot)
2) Got out my meter and took measurements (see results below)
3) I remember reading on another troubleshooting thread to check Q11-13. When I checked values with my meter, I didn't get readings too far outside the range printed on the build doc. (I replaced them anyway to see if it made a difference; it didn't.)
Here's what I haven't tried:
1) Throwing the PCB against the wall
2) Hitting it with a hammer
3) Getting a new Speed pot.

Any thoughts?
