I'm nearly done with my Pitch Witch build, but I'm stumped on getting the LFO up and running.
Here are the symptoms: Delay part works perfectly, but neither LFO or indicator LEDs are lighting up. I also think my dual op-amp chip is heating up a bit, and I switched chips to no avail. I used TL072 instead of 4558, which I think should be okay.
Here are the voltages on the chip:
1 - 6.7
2- 2.52
3- 4.33
4- 0
5- 5.2
6-4.33
7- 2.56
8- 8.72
Any help would be much appreciated, thanks!
