Yes Igor.... and your 1176 looks fabulous.

Cool....thanx....great idea about having 2 photo-cells.
This makes it really useful.
Time constants are set by LDR characteristics (on/off time AND memory effect of CdS),
so, there are 2 different compressors inside. Different CdS cells have different memo effect BTW.
For "industrial" use, it is bad, for audio it is YUMMIE!!!
Considering non-linear frequency response of EL panel versus linear LED, as well,
there should be 2 different behavior compressors inside.
Cool, really, cool. I drooling on this idea.
Are you feeding the opto's LED from diode bridge or as-is, direct, half-wave?

Are you feeding the opto's LED from diode bridge or as-is, direct, half-wave?

At the moment direct through around 470k.
I need to address some power issues before testing.

Hi All,
