Color organ crisis

[Faizi]

found this circuit on net. trying it for days but the damn circuit wont work. the only change i've made is giving the audio input 4m a LM386 which is then reamplified through the 1st opamp of lm324 (as in circuit ) and the other big change is that they are both being powrd by a pure dc supply(separate) rather than the common rectifier as shown in ckt.

what m i doing wrong ?

The first opamp does not have a DC bias voltage so its output will be extremely distorted rectified audio.

but wont we be needing the outputs of opamps to trigger the SCRs?

 

[audioguru]

The SCRs are triggereed from the rectified outputs of the filter opamps.
