Dual LFO

Two schmitt trigger and integrator oscillators, each giving a square (10 V, -5 to +5 V) and a triangle (6 V, -3 to +3 V), from about 45 seconds a cycle to 830 Hz; and a difference rectifier taking the two triangles and sending their difference to a positive or a negative output. Printed 2xLFO on its panel.

Key features

• Two LFOs, each with its freq and fine knobs and its sqr and tri outputs
• The difference rectifier's -ve and +ve outputs
• A lamp for each LFO
• 8 HP; current draw as ModularGrid lists it (Nonlinearcircuits publishes no current draw, depth or assembled price: it sells the DIY PCB and panel)
