CSI Premier 75W and Hakko 936 Solder Station Teardowns
Todd Harrison @ toddfun.com did the teardown of the CSI 75W solder station as well as the Hakko 936: The Hakko of course had all analog circuits using operational amplifiers and potentiometers as well as a temperature sensor in the iron tip to signal back to a triac chip controller which would trigger the triac to push 24 V AC through the heater in the iron.
