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). | 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. | |||
