i built a bubba oscillator of 50hz frequency and had to buffer the point where the signal has lowest distortion using TL084 for the original oscillator and TL082 for the buffer circuit.i then built a triangle wave oscilltor of about 3000hz - 10000hz range and set it to about 5000hz but when i wired up the comparator using LM393 to get PWM signal i am getting strange signal and i dont know what else to do here are the pics of the circuit.
am kind of confused on what am doing wrong since i was able to get the bubba to oscillate well at 50hz and the trinagle to oscillate well between those frequencies and keeping it at 6000hz for pwm but i dont know whats happening.
