Op amps are 1.1435:

This is the original schematic, but it looks funny to me. I think that there should be a 100k resistor at the
(-) input of the second opamp to make it a pure inverter. As it is, that stage would have a very large
voltage gain, unbalancing what I think works as a full wave rectifierlcurrent source for the LED in the
compression feedback loop. I would expect that the proper circuit is as shown in the fragment below.

I think the VTLSCZ LEDfLDR module could be replaced with a CLMGOOO if you could find one of those.
