Early Version of Blue Lantern Clones Red VCO
The Red VCO started it all. It offers the basics: SAW, SQUARE, and TRIANGLE.
The Saw and Square wave is selected by a C&K toggle switch, it has a shared output Jack labeled WAVE.
The Triangle has it's own output.
On the PCB I added a Jumper similar to those CMOS motherboard kind to select if you want it SAW or RAMP based.
