Duel OSC, Triangle Wave Synth

This box contains two triangle wave oscillators with controllable pitch (the big knobs) and drive control for each oscillator creating (almost) square waves. Balance control is the middle knob at the bottom. Powered by 9v DC adapter or battery. I started with the circuit from this article on hackaday and cobbled it together on DIYLC. Constructed on …perfboard.
