Hi All, I hope you're well...
I'm adapting THATCorp's One Knob Squeeze circuit (pdf attached) to use their 4315 instead of the 4316, the only difference is the 4315 can take a 9V single supply, and the 4316 cannot...
I'm also using TL072/4 instead of the recommended MC33178 op amps because thats what I have on hand, and I'm not concerned about power consumption just yet.
I've breaboarded the circuit (attached) a couple times, and it's just not working out. I've combed through it a zillion times, changed just about every component, and still I cannot get it going.
Can anyone spot anything glaring that needs to change?
I circled the first opamp, because while there is voltage signal going into it, there is no signal coming out. I realize this opamp is used to convert it to a current signal, but I'm not getting any signal output.
Any ideas?
Are TL072/4 a poor choice for this application? So poor that they're somehow crippling it? I can't image there's anything wrong with them...
I've attached my schematic along with THATCorp's schematic in case you're curious.
Ignore the balanced line receiver and line driver output, I'm not including them in the breadboard.
Thanks in advanced!
