 The SC504 uses some custom Tek ICs, namely the [[155-0124-00]] preamplifier (U4345), [[155-0109-01]] trigger (U3238), and [[155-0122-00]] A-B logic (U3158). There are two passive input attenuator hybrids (HY1520, HY1420) and two [[155-0161-00]] attenuator/amplifier hybrids (HY1530, HY1430).
-The power supply uses the pass transistors provided by two mainframe slots.  On the left mainframe slot covered by the SC504, the pass transistors are the only connections.
+The power supply uses the pass transistors provided by the two mainframe slots that the SC504 covers.
+Those on the right slot provide ±20 V from the mainframe's ±33.5 V rails, those on the left slot make +5 V from the +11.5 V rail and −5 V from the rectified 17 V<sub>AC</sub> supply.  Power is drawn from the right mainframe slot,  the pass transistors are the only connections on the left slot.
