SCRF-1 pin 12

We received the 451L chip this morning. Then we installed it on circiut board. The right picture shows the firing angle wave forms with/without H.V. pulse modulation. When I tuned the voltage amplitude, the firing angle voltage was followed to change.

Unfortunately, there was not any output yet. I checked the wires and found pin 12 on SCRF-1 was losing. Maybe this caused no high voltage.
