Simple color organ


Posted on Jun 18, 2012

Transformer Tl can be any matching transistor type in the range of 500/500 to 2500/2500 ohms. No connections from the SCR or its components are connected to ground. For safety's sake, keep the 117-V line voltage from the amplifier connections— that is the reason for using Tl. To adjust, set potentiometer Rl `off` and adjust the amplifier volume control for a normal listening level.
