Hello everyone. I would like to clarify some doubts I have about the Threshold SA12E diagram.
In the universal FEB schematic:
-Where is the cathode of the diode in U1 (CNY17-3) connected?
-Are the thermistors NTC or PTC?
-Which of the three thermistors is connected to the heatsink?
-In transistors Q14-Q15: Where are their collectors connected?
-Where are the emitters of transistors Q1-Q2 (-7V, +7V REG OUTs) connected?
Thanks in advance to all those knowledgeable in the matter willing to help. Blessings.
