Yep, but math aside, i don't see any illumination from the Bulbs.  I see AC swing post coupler to Optical units. So that's why I suspect them. Where is the resistive LDR portion tied to in this puppy, output section probably but in parallel with what resistors? Cathode???  I don't see fixed bias voltages on any grids, but perhaps its in parallel with a leak resistor or something. Should just trace it out, but I aint really got the time right now.

I'll get back in there later tonight and get more data together.

Thanks again, don't feel so alone with this one cuz of yall!
