LIGO Document E1300114-x0
- Details of the component changes to render this design insensitive to loss of a single power supply.
- In response to the single supply failure mechanism intrinsic to this design, the following components were changed: U2 from AD8597 to LT1128, U8 & U10 from AD8675 to OP27, C31 removed to aid stability of LT1128. Reverse biased diodes are added across the main filter caps in the + and - 15VDC rails.
