Wonderous Comparators...

I'm burning-in several of Ken's Gated Comparators tonight, and I must say that a total pleasure they are to play with! (also with the lights dimmed-down, the music they're making is quite hypnotic along with all of the dazzling LEDS)! (Thanks Ken) Cynthia

Re: Extra component on VC Divider?

Those holes were for an "emergency" spike suppression capacitor if I found it needed one in that part of the circuit. It ran fine without it, so you can leave it out. The cap would have been around 10 to 20 pF if it had been used. Ken >Hey Ken - > >There's a spot for a component

Re: Super Psycho

2002-08-16 by sasami@hotkey.net.au

The most likely problem is the switches themselves, or your wiring to them. Make sure you haven't got any wires swapped. If both tri and square are very weak, it can't be the TL072 used for the triangle buffering. If all other oscillators are loud enough, it can't be the TL072 us
