Just a heads up to anyone else assembling last minute Dirkcheap SSRs. Just finished troubleshooting 7 of the 8 that I just assembled and found I had 7 bad optocoupler ICs that were sent with the kits. Sockets were used and they were not installed until all soldering was complete so they were not subjected to heat. Luckily I had enough new ones on hand to swap out but what a headache.
