- R10, R11 and R12 control the response of the different lights.
- The circuit can handle up to 300 watts per channel.
- This circuit is NOT isolated from the 115 Volt line. If it is used with the case opened or not installed in a case, you could recieve a bad shock or be killed.
- You can also use the Teccor S2003LS1 SCR for SCR1. These give better sensitivity and brightness than the 106B1 units.
- Thanks to James Maloway for redrawing the schematic.
