I found the CA3059 here: CA3059 pdf CA3059 datasheet Zero-voltage switches for 50Hz-60Hz and 400Hz thyristor control applications 16.3415 Linear ICs Power Supply Support Circuits Zero-Crossing Trigger/Phase Control American Microsemiconductor CA3059 available at 16.3415. FRE
I vaguely remember having to make a change to the published circuit I used. I remember something about "sensitive gate triacs" and a series resistor. I'm trying to use brain cells that had info in them 40+ years ago. I've got the info "somewhere".
